Alan Kay: Normal Considered Harmful (2009)
From Viewpoints Intelligent Archive
								
												
				this is a kind of a fortress set
kind of the professor against the  students
 but the cable is short so
 I  have to duck back there periodically
  thank
 you all for coming out I believe  I'm the second prize
 in the raffle
 this
  this talk is
 is about some of the ways I
think about our field it's not  particularly technical
 it asks a lot of  questions
 it's an attempt to be critical
  without being a rant and
 it won't
 be  successful unless I can get you
 to  interact periodically there'll
 be a  couple of opportunities early in the
  talk and the title of the talk
 deals  with two
 properties of frogs
 one of them  is
 that their nervous systems like all  nervous systems
 are mainly interested in  differences
 but unlike
 us they are able
  to habituate very rapidly and
 so it is  amazingly true
 that if you put a frog in  a pot of water and heat
 it up very  slowly they will not get out
 because the  the difference
 is that their nervous  system are detecting are
 too small over  the unit of time that their nervous  systems work
 on and they
 will just stay  there until they cook and
 of course we  aren't like that
 and the
 other  interesting property of flies which i  think is
 one of the most amazing
  properties and it was first
 discovered  in a landmark
 paper called what the  frog's eye tells the frog's brain
 and  you may or may not know that the
 retina  in your eye is acts
  part of your brain is actually extended
  out from your brain and your eye  actually
 does a little bit of thinking  right
 in the eye for efficiency reasons
  for frogs their eyes
 do a lot of  thinking thinking
 that actually triggers  behavior and
 so
 one of the most  interesting things about a frog
 this if  you take its natural food which your  flies
 paralyze them with a little  chloroform
 but peep them alive and put  them
 in front of a frog it will starve  itself to death
 because its conception  of a fly is
 not that if you
 take oblong  shaped pieces of cardboard
 and throw  them at the Frog it
 will eat them until  it's stuffed because
 it's built
 in  pattern for food is an
 oblong thing  that's moving and
 there's no limit to  the amount of cardboards
 that a frog  will try to try to eat
 so one of the  ways of
 looking at this is that the  frogs both
 of these conceptions of  normal that the frog
 has are quite  harmful for it
 under certain conditions  so it considers
 normal food to be oblong  things that move
 and it considers a
 non  change in temperature as
 far as it can  detect it to be quite safe for itself
so this is the famous Pogo cartoon
 this
 true of so many things about us  humans
 trace back some problem
 and very  often the
 trace is back not to physical  nature but to human nature
 and I think  this is the
 problem in many fields a  little
 bit later we'll talk about how  the biologists have
 dealt with some of  the same problems that we have in  computing
 so
 first so here's our first  opportunity for interaction
who's that first guy Newton
 who's the  second guy
 Darwin and
 the third guy the  most famous face
 on the planet
 who's  that first guy
 who's the second guy
 nope  who's
 the third guy
 who's the fourth guy
  and who's
 the fifth guy pardon
 nope so  first
 guys John McCarthy
  never heard of him
so
 these guys are all magic
 people in  our field so
 John did many of the most  seminal things to
 this day in the
 field  of reasoning and programming
 languages  second guy is Ivan Sutherland
 he only  invented computer graphics and
in a way more interesting than most  computer graphics
 today probably if
 you  had to pick the most powerful
  groundbreaking distance
 from zero thesis
that has ever been done in our field  it's his thesis and if
 you don't know  what he looks like  then
 I'm sure you don't haven't read  that thesis and
 Engelbart so
 what did  angle Bart do okay
 what else did he do
kay so when
 I was giving talks in 2004  this is the question
 I asked every  audience at every University
 everybody  had heard of angle Bart in the mouse but
  most people don't realize that
 Engelbart  was the prime
 conceived of what we call  personal computing today and
 the prime  conceived er of what
 we think of as  hyper
 linking ideas together over a  network with
 collaboration between  people and the prime conceived
 ER of  what collaborative work would be like  and
 by the way he built all of this with  his research group in the
 60s and it was  demo to 3000
 people in 1968 41
 years ago  so an interesting thing here
 is to just  ponder the
 fact that even though you've  heard of
 Engelbart's name if you
 had  taken the trouble to type e ngle ba
 RT  into google within the first three
 hits  some of them you will be doing it right  now you'll
 find the bootstrap Institute  which have the
 75 seminal papers that he  and his group wrote
 and you'll also find  the videos
 of that what
mother of all demo  in 1968
 and yet in fact
 the internet and  personal computing were invented just so  you could
 do that and so now ponder
fact that you do know the name of a  famous person in
 our field from the past  and yet you didn't have the curiosity
 or  the energy to do that simple little  typing
 job so if this were physics you
  would all be dismissed from the field
  because physicists would not tolerate
somebody being in physics and not  knowing
 quite intimately what the  pioneers
 and developers of physics  including Newton
 and Einstein and so  forth actually did it's
 not an optional  idea but in computing
 seems to think  that it is so part
 of my thing to get  you
 to ponder is I don't think computing  is a real field
 it acts like a pop  culture it
 deals in fads  and it
 doesn't even know its own roots  and worse
 than that it does not know  about the really good things that
done in the past for instance  Engelbart's conception
 if you were to  look at it you would see far exceeds  what
 Tim berners-lee was thinking about  and
 his demo far exceeds what you
 can  even do on the Met and the web today and
  why can't we do it today because the
  people who set up the web did not know
about Engelbert and did not take the  trouble to see if
 anybody had been  thinking about this so this is the mark
  of a pop culture this guy is the world's
  greatest computer designer
 designer  among other things of the Burroughs be  5,000
 and that machine implemented in
  hardware what we would call a byte coded
interpreter for a higher-level language  today today
 we can only do it in  software because Intel and Motorola  don't
 know this is a good idea  the bharden
 knew it was a good idea in  1961 and designed
 and built with borrows  a computer that
 could do that and a lot  more so
 you can't be in computing and  not know what Barton did and
 not know  who he was and this guy
  was part
 of the for funders
 at ARPA that  funded the fundamental
 research in the  60s and he was also the
 guy who set up  Xerox PARC his name is Bob Taylor and
 as  they used to say in the old days
 no  bucks no Buck Rogers so
 part of the  reason the past
 actually was quite a bit  more successful
 in the present is  because the funding was done
 better and  people who knew how to run research
  groups like Bob Taylor you
 had to do it  so I knew you
 were going to give that  response because
 okay how about this  picture
 parted
 yeah so both of you
 were  right so iliac one
 was a johniac
 the von  neumann princeton
 computer and was built  here at the university
 of illinois and  they actually got done before
 the  Princeton people did so there are  several of these
 machines built all of  the same plans and the Princeton
 people  are a little bit late
 about that I
 just  love this computer
 so
 this is one of the  first supercomputers to ever be done  happen
 to be done right on this campus  called iliac 2
 and it had the
 register  pipelining
 idea even before the IBM  stretch did
 so this was a really serious  computing
 machine done on this campus by  the professors and
 the students kick ass
how about
 this
 play-doh what was played  up
 yeah
 then
 it wasn't exactly the first  graphical interface
 but so this is a  system that was built
 by dom Bitzer and  colleagues
 here at the university of  illinois is one of the largest
 funded  computer-aided
 education projects in  history
 there are a lot of people worked  on this and
 give you the scope of it  2000 terminals
 connected to large  control
 data mainframes and
 the
  flatscreen displays on these terminals
were actually invented here at the  universe of Illinois so they could
 make  flat screen display terminals and why  did dom
 Bitzer want to do it because he  wanted to back project colored
 slides  they wanted to have something that could
  do multimedia education so when you use  one
 of these terminals in the top of  these things
 was a Kodak slide carousel  and
 so when you went to learn something  you get a slide
 carousel that would have  the high resolution images that were  going to be part
 of it put it in there  and then you had a 512 by 512
 plasma  panel display this
 is the first flat  panel display in the world
 that was  actually practical done right here at
he University of Illinois and with  cooperation from Owens
 Corning
 shouldn't  this makes you proud to be in
University of Illinois computer science  department right you
 should be because  this
 place is one of the leaders of the  world but
 guess what you
 guys haven't  done a supercomputer for a long time
 you  haven't done a project like this for a  long time
 you're using vendors computers
  and vendors software and guess what you  can't
 invent the future by using vendor  stuff it's all
 looks back in the past  the best of it and most
 of it is  exactly the wrong way of looking at the
  future so Illinois like
 most places like  UCLA where I'm on the faculty
  most of the major universities
country have given up the future in  favor
 of something else most places in
this country when it was really hard to  design and
 build computers built around  yes
well no I don't
 think so because this  assumes that there's something good
  about what you can buy from vendors and
  I think
 when that's the case it's  worthwhile buying
 from them but in fact  the
 vendors are struggling like mad  themselves because
 Moore's law marches  on and they
 don't know the first thing  about doing parallel computing for
example somebody needed to be doing that  a university
 is the right place to do it  so not
 enough has been done and
most of the great inventions come out of  a kind of a
 something as more like a  university culture and by
 the way there  is a technology called fuel programmable
gate arrays in which regular students  like
 you and me can sit down and make
 a  thousand processor
 supercomputer by
  writing not a lot of pages of code  because
 the state of FPGA is of in the  last year
 and a half or so has gone  through a knee of
 the curve and is now a  serious contender for
 allowing people to  do huge multi processing
 projects by  themselves if you're interested
 we can  talk about that a little bit later
 so
me years ago my wife who's a writer  and an
 actress and an artist and so
 she  had one of these huge Mac cinema
displays on her desk and she showed me  this
 display and
 was kind of
 odd over  here
 she had all the applications
 that  she used that were WYSIWYG she
 really  liked them and here all the app the
stuff that she does on the web and none  of it was WYSIWYG
 at that time and
so
 she said in these apps I can see and
  do full WYSIWYG opera authoring and
 the  web browser has all these modes and
 I  have to type through a keyhole and I  have to
 wait to see whether what I did  was ok and all these
 stuff and and why  is that she
 asked me and I said well  it's
 because the stuff you like was  invented in
 the 70s and the stuff you  don't like was invented 20 years later
  what do you think
 about that how
 could  that happen it's not that
 people don't  make mistakes
 but you like mistakes to  go away
 yes
 yes and it's
 quite  interesting
 of course where was this
  invented
 web browser was done
 by  University of Illinois students a little  bit after
 that age of people that made  playdough terminals
 and supercomputers
o in 1993
  here's mosaic and
 one of the interesting  things about mosaic
 was was it remotely  is nice at what angle
 Bart had done in  68 and it was full
course they didn't know anything about  it Tim
 berners-lee who did do the web
 at  CERN was quite chagrined
 when it was  pointed out to him just
 the sweep of  Engelbart's ideas he was very
 upset that  they did what they
 did the way they did  it and even
 more interesting
 five years  six years before the web
was HyperCard  at Apple which
 is the perfect model if  you think those of you are familiar with  HyperCard
 it's the perfect model for  what a web browser should actually
 be it  had full WYSIWYG editing
  right in the thing
 and anybody who  understand this at
 all would have  realized oh yeah this is the perfect  thing
 it already has hyperlinking in it  there's an editing model
 it's been  tested on four million users we know it  works
  nope a bunch of hackers
 got together and
one of the ways to think about
 this is  Engle Bart invented the wheel and Bill
Atkinson with HyperCard invented a  better wheel
 that's really great and
 and  unfortunately
 I can't even give the web  browser
 the flat tire award and
 or even  the square wheel
 because you can imagine  improving both of those to
good but you know when you invent a  broken wheel
 there is it isn't
 obvious  what the wheel is or
 it doesn't even  work at all flat tire you can you
 can  run it at the expense of the tire
figure out what the tire should be in a  square wheel you
 can run it and figure  out it should be rounder but a broken
wheel won't work  and so attempts to
 fix a broken wheel  produce more variations
 of a broken  wheel and we've
 had 16 years of them
 ok  so
 let's a man here you are today
 let's  suppose you're at a computer
 science  those you had an undergraduate degree in  computing
 from back then and
 you're  faced with this idea
 that yeah there's  this internet that's going all
 over the  world and
 it's going to be not just
consumption mechanism for stuff that's  already there but
 everybody is going to  be an author and a publisher and
 so how  would you solve that problem
an idea  what
 would your approach be to it  knowing what you know today or
 even what  you would have known back
this
 is a complicated problem right  there six billion
 people in the world  there now a couple
 of billion nodes in  the internet there
 is zillion everybody  wants to do something yes
 the
is how much work do you want it you want  to solve this problem really
 well but  how
 much work do you want how much do  you think your browser should actually
  know in order to solve this problem  really
 well because
 think of everybody  has a different interest in the
 web  there's many
 kinds of media you don't  even know what kind
 of media is going to  be invented and for any given kind of  media
 there  like video there are dozens of different
  codecs and just think of the what
problem is so how would you approach  this problem
 yes
well but
 suppose they want to write  machine code because they know how
 to do  something really really fast
 like
suppose somebody wants to implement  their own codec
 yeah
 but you're you're  partly partly there but
 I'm talking  about letting people
 exercise their  creativity and
 sometimes they're going  to need the
 most every resource on the  machine to be
 used but
 of course we  can't allow them to take
 over the  machine so what would you do
yeah
 so it's closer it's
 almost a good  idea after 16
 years including see Google  has some real interest
 in this because  Google
 did v8 because they couldn't
  stand to have the normal conception of a  slow
 JavaScript and they're
 doing the  thing that you just mentioned because
  they realize that
 people who have ideas  also
 so ok
 so
 this is an interesting  thing
 so
 it really should be like an  operating system kernel right
 the
  operating system kernel controls address
  spaces that can confine computations  completely
 therefore you can actually  allow
 any binaries to come down and be  used you can
 completely control what  goes in and what goes
 out and all of a  sudden
 your browser is simply something  that allows
 bitmaps canvases that you  give to
 these things to write on to be  displayed so
 this it's there's nothing  you have to do because
 you don't want  it's like the
 the the good
 idea in UNIX  was hey
 we don't want a big operating  system we want
 the tiniest kernel we can  have and then we want to use
 address  spaces in order to protect everybody  from everybody
 else so this is this is  operating
 system 101 this is well known
  all the way back in 1965 and 1966
 it
should be the first thing that occurs to  anybody so I figured somebody
 young so
  this occurred everybody in the 60s and  70s knew
 this is the way to do it we're  all surprised it wasn't done
 this way  but I figured somebody in
 the current  generation would have figured this out
  and so I went looking on the net using
  Google looking for downloadable binaries  and
 stuff like that  and I
 found this grad student in Cornell
  in 1997 Oh far Erlich
 son who is from  Iceland wrote
 this paper in this paper  if you just type in
 the title of that  paper you'll find it's an HTML document
  that he put on and on the net in
 1997  and his problem by
 the way was hey I  want to run a Kodak I want
Kodak and I don't want to have a system  bin worried about
 whether it's an  executable or not so it's this thing  should be like
 an operating system so of  course I
 wrote an email to him he's at  the
 University of Iceland now but on  leave to Microsoft up
 in Mountain View  and had
 a long correspondence with him  on the
 pathway of these ideas and
 he  started a company that Google
 acquired  and
 is using a couple of the ideas but  interestingly not
 all of the ideas in  this paper
 which actually solved the  problem very nicely so
 this is an  interesting thing where it
 wasn't that  somebody didn't understand what
he problem was and what the right  solution was it's that
 the larger mass  was
 quite happy to plunge into a de  facto standard
 even though most of the  original people to
 use the web we're  computer scientists they didn't protest  that
 this was a very bad way non  scalable
 way of doing it  they just plunged in and sixteen
 years  later Google is and other companies are
struggling to actually use the internet  the way it was intended to be
 that's  pretty interesting to me
 now another  story is
 35 years ago the
 kind of  personal computing we think of today was
  done at Xerox PARC in 1973
 and
much
 of the paraphernalia we have today  was done in about ten
 thousand lines of  code Smalltalk code
 written for this  purpose and
 so another
 question you  could ask is well jeez
 the browser is a  terrible
 design but it does have  JavaScript in it and
 it turns out  JavaScript even though it's slow
today's standards it's faster than an  Alto was back
 in 1973 so hey why doesn't  somebody
 just do a whole personal  computing system in Java
  like everything Windows
 interface the  overlapping
 idea is two and a half D  graphics like every
 damn thing in it and
so basically what you're doing is just  drawing a line and saying
 this stuff is  crap but
 it runs and I
 should be able to  write 10,000
 lines of code so
 the basic  idea take the rubble that's the browser
  make an arch out of it get
 the guy who  did the job originally at Xerox PARC
 Dan  Ingalls to do
make
 stronger classes in JavaScript make  a better
 graphics system make the
widgets and stuff to make an application  development system and
 and an  interactive
 development environment and  if you want
 to try this out I
 don't have  time to do
 it but this is what it looks  like running completely in a
 browser  took about five people six months to
 do  could have been done any time but
 nobody  knew how to do it has
who had done it before in the past  because nobody
 knows how to do a system  like that in
 ten thousand lines all
right so this is a craft that was lost  because
 people have been used to just  building on the stuff that's
there so when this new thing came along  it wasn't anybody
 around who was working  on it that could just say okay
 we want  to have something like the WYSIWYG
interface and authoring tools and  everything else that we enjoy
 on the our  regular personal computers and we want
o be able to do all of the stuff in the  browser so
 this
 is called the lively  kernel it was done while dan
 was at Sun  you can look that up so
 here's another  way of looking at this is if
 you take  the
 minimum bar I would say the general  practice
 today is below that minimum and
  take a qualitatively better bar
 I'd say  that the best that was
 done by the ARPA  park community like the Internet and the
thernet and personal computing and  stuff like that was better I
 think the
  best knowledge of today is better
 than  that it's not that everything
 is back  slid absolutely not it's
 not that the  people are
 not as good as they used to  be I'm convinced
 that there are more  people of high
 ability available today  than there were 40
 years ago there's not  a complaint about the people
 but I'm  complaining about the outlook
 of the  that
 produces such poor results
 now the  problem is that the real bar today
 is  above the best of what
ime ago and it's above the best  knowledge today this
 is the problem this  is why companies
 are writing millions of  lines of hard to deal
 with code because  the ability
 to scale is potentially
  there yet you have a
 question okay the  ability to scale is potentially there
but the knowledge of how to do the  scaling is not
 there by anybody so the
real way of looking at this is we need  something like that
 today  and we
 have to think figure out  something that's a little bit above the
best knowledge today that has a  stair-step built
 into it to get up to  where we are also
 things are just going  to get worse than
 they are now so this  is a very very difficult
 problem it's  been fomenting for years I
you are aware of it in one way or  another I'm just
 I'm pointing it out not  so that you believe
it but just so you think about it  yourself
 so
 back to a couple of ideas so
  here's the printing press appearing in  1450
 and whenever
 a new idea appears you  get two things
 you get news
 news is  stuff that's incremental
 to what we  already know this
 is why you can tell a  news in five minutes
 hey a train just  crashed we
 all know what that means so  the
 reason we want to know is we're  excited by changes like that
 but we  don't have to have it explained
 to us  there's no epistemological hurdle
 we  have to go through to understand that  and
 so the original idea for
printing press was to do what monks do  but do it cheaper
 and there are a couple  of other side
 things but when ideas
 are  really interesting is also do
  and knew is
 by definition not like
 what  we already know so
 there's no news about  new there's
 nothing you can tell  somebody in five minutes about
 what new  is and
 new
 for the printing press was a
  huge change in Outlook for our planet
  and one of the changes was
believing to arguing in a new and  special way and
 it took 150
 years to go  from the Gutenberg Bible to Galileo
 two  hundred
 years to go to Newton and three
hundred plus years to go to the American  Constitution
 but one was the driving  force for
 the these other things now  interestingly
 about 50 years after the  printing press there
 were people who  were writing in Europe like Erasmus
indicated that they understood  completely what the printing press
about and what was going to happen from  it but
 the larger mass of humanity took
  150 to 300 years to actually gradually
  change their thinking around to start  thinking that
 way
 ok Leonardo had a high  IQ but
 he couldn't invent a
 single  engine for any of his vehicles so
 if he  had an IQ of 500 and you were born in  10,000
 BC you're not going to do a lot  you
 can outwit everybody before they  burn
so Henry
 Ford was not nearly as smart as
Leonardo but he was born in a better  century so
 he revolutionized  transportation
 so knowledge almost  always Trump's
 IQ and
 the
with knowledge is most of us know a lot  but it's
 not it's not good knowledge
  might even never have been good  knowledge
 but sometimes it was good  knowledge and now it's bad knowledge
 so  knowledge is this double-edged
 sword  very powerful when
 we have it right and  the thing that gets it right for us is
  when somebody is able
 to change the  outlook the fancy word
 is  epistemological stance the way we  actually
 look at things and Newton was  one of these people
 so he changed what  knowledge actually meant and
 he changed  what engineers
 and more practical people  could do and so
 the line there is point  of view is worth ad
 IQ points you go
from a weak way of looking at something  to a strong way of looking
 at something  that's like getting an extra brain and  Newton
 is a perfect example because  before Newton the
 smartest people in the  world couldn't do things that a high
  school calculus student can easily
 do so  calculus is like getting
 an extra brain  and it makes you much
 much more able  than a genius
 who doesn't have it
so these outlook changing things are  really critical
 so I think of knowledge  of
 silver outlook as gold and IQ as a  lead weight
 I believe one
 of the biggest  problems with computing is in
 a sense we  have too many smart people
 it attracts  cleverness and
 you can do clever hacks
but the clever hacks don't
 scale well  and it's very hard to build a
into software it just stays around  forever and
 so what what's actually  happening
 is kind of something like  building a large garbage dump
 that makes  it the odor of which makes it
 very hard  to think about other things so
 if we  take news
 or normal we can think
 we can  solve problems avoid obstacles
 beg every  once in while we
 have an outlaw thought  but
 we went to school we went to church  we
 have parents we live in a world of
  normal and for most human
 beings the  world of normal trumps any weird
 new  kind of idea
 try having one when you're  going
 out for tenure
 think of all the  different reviewers who
 already have an  idea of what computer science should be  about
 it's crazy
 and people start  winding up gaming the system and
 doing  lots and lots of little papers that mean  nothing at
 all in order to get
 the  approval of these reviewers whose
 ideas  about computing might be completely
 off  but every once in a while
 maybe
 in an  unguarded moment like taking a shower
getting up in the morning or something  you
 get a Kirpal
 not that this kerpow is  true most
 ideas are mediocre down to bad
  but at least you've got a new Kirpal
 and  these career paths
 are the things that  need to be tested out science needs
as much as art because you have to get  ideas from somewhere
 so when you have to  be in a state to
 get these cows and then  you have to have the tools to be
 able to  discard the Kirpal if it turns out to be
  a really stupid idea after all
  so think about this is
 if the pink plane  there is reality
 then what do people  think the blue plane is
 like insanity  you
 are insane
 and learning
something that your brain isn't well set  up for could
 require almost as much  creativity as inventing
place because you have to invent it  inside your
 head and so
 you can say that  normal is the
 greatest enemy with regard  to creating
 the new in the way of  getting around this
 is you have to  understand normal not as reality but
  just the construct and a
 way to do that  for example is just travel to a lot of  different
 countries and you'll find a
thousand different ways of thinking the  world is real
 all of which are just  stories inside of people's heads that's
  what we are to normal
 is just a  construct in to the extent that you can  see normal
 as a construct in yourself  you have freed yourself
 from the  constraints of thinking that this is the  way the
 world is because it isn't this  is the way we are
so
 changing people's minds is hard  because of this
 so I'm going to give you  just two simple dimensions
 so this is  the whole
 human race just
 5% of us are  intrinsically interested
 in ideas 95%
 of  us are interested
 in new ideas and tools  just
 so far as they contribute to our  current goals
 so once we have a goal we  tend to be fastened
 on it you can  imagine why so
mething new  we
 immediately evaluated in terms of our  existing goal structure it
 doesn't fit  into our existing goal structure forget
  about it 5% of us
 though are get  interested in whether
 this is an  interesting idea or tool intrinsically  so
 let's take a different dimension
 this  is one that has been
 well studied about  85% of us generally
 do things for the  approval of others who
 are social beings  after all
 people use
 the Internet  very much for confirming
disconfirming what they should be  thinking about by finding
 out what their  friends think about so
 this is  completely normal to human beings about
  15% of us
 have many of our motivations  be internal
 so if we do something that  we like we
 don't really care what other  people think and
 to the extent that  these two dimensions
 are independent you  get
 something like this and
 so 1% of us
  love
 things for their merits and we
  don't care what people think
 you can  imagine what do those people
 do with  their time and the
 other extreme is  eighty percent of us are
 instrumental  and
 our goals
 are primarily determined  by whether other
 people approve of them  so
 think about what these one-percenters  actually
 do and think about
 what happens  to those ideas
 when they try and get  society to change
 and then
 the other  extremes are outer
 ideas and tools and a  very
 dangerous group of people who are  inner and instrumental
 there are a lot  of managers and politicians
 in this  group
 dictators of countries and so  forth
okay
 here's another analogy it was an  old one and
 has been shown to be a good  one that when it
 rains it's somewhat  random as to where
 a little gully starts
  but the gullies have the property
 of  being self optimizing once
 you get one  started they are more efficient at
getting water through them and so they  erode faster
 and so pretty soon
 you've  got something human
 memory is rather  like this
 basically once we get  comfortable about something
  we are extremely homeostatic
 about it we  love our gullies
 and they take a long  time so
 a little bit like the Frog in  the pot occasionally
 our gullies will do  us in because
 we can get awfully  comfortable and then get surprised
 by  something like AIDS which takes a long  time to
 really show up and
we humans have a hard
 time forgetting  things we don't have the men in black  stick
 for when we have a bad idea
 or  learn something that isn't actually not  good
 for us we can't erase it and so
have this interesting this is something  that's been noticed in
 programmers there  very large percentage of programmers
  think like their first programming  language for
 the rest of their life no  matter what programming language they
learn afterwards if you look at their  code it looks like that you
what first language they had because  that was the first
 time they got fluent  those were their paradigms for thinking
  about problems so
 human beings are  actually quite anti learning
 and
 in fact  most of these things are
 built into our  genes
 for example we are a coping  species
 not a product not a species that  likes to progress we're
 basically social  we all have language
 so more than three  thousand cultures have been
 studied by  anthropologists and every single one of
them has about 300 things in common and  so
 the determination is that these  things are not things
 that were invented  but are actually
 built into the genes a  very human  so
 once you've and by
 the way if you  look at these things you can realize if  you want
 to make a lot of money build an  amplifier for any of
 these using  technology and you'll win
 see why so
 you  know when television came out the
 movie  people didn't think it was going to sell  but
 they didn't realize it was a fantasy  amplifier that was going to go in  everybody's
 home of course it's going to  win
 but they couldn't understand it for  what
 it was and
you can take a look at things that have  not been found
 in every culture and a  couple of the interesting
 ones are at  the top
 progress as it was called
18th century is an invention  it's an idea was
 first articulated not  so many hundreds
 of years ago because  back then was the first time when people  realized
 that the world that their  children are going to die and
to be different than the world that they  were going to die in and
 so the people  who wrote the American Constitution even  suggested
 that there'd be a new  Constitutional Convention every 50
because things are going to change  fortunately they didn't
 carry that out  they were unusual
 compared to our  current puppet politicians and
 the  things in
 blue they're the non  universals are harder to learn the
 ones  in the pink because they're not as
trongly built into us they all had to  be invented and
 so an accurate picture  of
 us is that we're pretty much
 cave  people with briefcases and
 there's  actually a group of people who study us
  as cave people with briefcases called  behavioral
 economists so
 if you've  looked at so one of the books is called  nudge
 by Richard Taylor another great  book is called
 predictably irrational by  Dan Ariely
 these are people who study us  as we
 are and why we actually make  decisions even against
 our best  interests and
 most of these decisions  are made because of
 things that are  built into us and this
 would be a  humorous picture except that the cave
guy with the briefcase has an ICBM in  his briefcase
 and a lot of other things  that are
 too easy to invent for  technology and the
 wrong kinds of things  for K people with briefcases to
 be  carrying around
 so
 a lot of what's going on today in  technology
 in general not just in  computing is basically for
 marketing  reasons we automate the pleistocene
 so  if you look at what
 is being sold and  used on computers there's almost nothing
that wouldn't be completely recognizable  to a cave kid
 right
 there's hardly any  new media on computers
 it's all  imitations of old media and most
has to do a storytelling of one kind or  another
 very
 little a little bit has to  do with those powerful
 ideas in blue  okay
 here's another thing I think you're  all familiar with that in
 a short period  of time change appears linear
 but
 often  that's just because you're looking
 at an  exponential curve at two finer grain
 so  these are big surprises for many
 people  so
 for example with silicon
 in round 65  we had Moore's
 law and that
 allowed us  to have a very different look at
 what  was going to happen and we use the
Gretzky theory of hockey anybody know  what that is
 yes that's
 right so they  asked him why are you so much
than everybody else and he said well  everybody just goes where
 the puck is I  go where it's going to be so
 this is a  good idea because it takes time
 to  invent things so if you invent things
for where the puck is you're going to be  behind by the time you
 get done so
 what  you'd like to do is to know
 what that  technology is going to be out there
 and  the wonderful thing about computers
 is  you can get that
 by just spending money
that's all
 it is that's the easiest  thing for Americans to do we just love
  money and we make tons of it
 so for  example that's what the University
 of  Illinois did when they did iliac 2 they
  wanted to get five or ten years in the  future in
 computing so they built this  supercomputer neuter enabled
probe into the future and it cost  millions of dollars so
 what if they
built something that was not as a  compute supercomputer
 at that time all  they'd learn is obsolete stuff
 there was  not going to be usable later
 so a park
  we looked at about
 12 years or so to the  late 80s and
 said we want a computer in  1973
 that will compute like the  computers are going to compute somewhere
  between 1985 and 1990
 those cost
 $22,000  for us to make we had to invent them
build them we built about 2,000 of them  and
 so 22,000
 in those days was worth  about 80,000 today right
 so it costs  80,000 bucks to have a 1989
 Mac but if  you had in 1973
 just think of what you  could do
 that can convened all the stuff  that the 1989
 Mac was going to run 1989
Mac would have to wind up being like  what you did
 because nobody else would  have the time to
 invent this takes years  to invent good things
 so when I come to  a university
 and I see students using  current day laptops it
 drives me crazy
ou're in the past  you're
 not even in today and
 just think  about the scope of the stuff
 that's  already been done you need a lot more  leverage
 the way to get leverage is to  get a ton
 of computer power and write  very simple
 non-optimized languages
 that  run very very quickly
 and you should be  able to do them every couple of days
  to get power you should be able to just
hrow them away use them like Kleenex  because
 it's rather easy to write things  like that if you don't have
and the way you don't have to optimize  is make hardware that
 runs a hundred  times faster than what you've got today
  so unless you do that you can
 only do  incremental stuff today
 so a lot of the  incremental ISM today
 is the lure of a
  cheap computer when it's actually
  standing a lot of people's way okay
  and so
 I think the last set of ideas  here is about
 problem solving and one
my best friends who died just a couple  of years ago it's
 one of the great  problem solvers in
 fact was awarded the  mechanical
 engineer of the century award  in the 20th century  it's
 one of greatest awards any engineer
  can do it this guy was completely
 magic  about solving problems
 so BAM powered  flight is
 an idea that's been around for  a long time and
 so Henry Kramer's idea
  was well I'm going to offer a large
  prize like $100,000
 but people
 tried to  win this prize for 40
 years and couldn't  do it
 Paul
 MacCready his
 brother-in-law  wound up with
 $100,000 debt and Paul
  being a nice guy he decided to assume it  to
 make his wife happy all of a sudden  Paul was a hundred
 thousand and dead and  he was driving across the Arizona
 desert  with his family one day
 and he had been  the world sail a sail
 plane champion a  number of times it was a fantastic pilot
  this is driving along looking at a hawk
  circling in the sky across the Arizona  desert
 and he suddenly realized that he  had seen the
 exchange rate of the  British pound that morning
 in the paper  the current exchange rate the
 40,000  pound Kramer prize was
 worth exactly a  hundred thousand American dollars
 so he  started thinking boy if I could win that
prize I could play off my  brother-in-law's death so
 he started  thinking about how could you actually do  man-powered
 flight
 he said the problem  is
 we don't understand what the problem  is really good people
 have been failing  for 40 years so this must be hard
 so his  idea was forget
 about man-powered flight  first
 thing we have to do is to try and  understand what the problem
 is you look  to see what does why aren't
 these people  doing this so what happened is people  were building very
 elaborate complex  designs
 for man-powered flight and they  would take it up and they'd
 have a crash  it would take them a year to rebuild the  thing
 so they're getting like one flight  every 8 to 14
 months and Paul said well  we need
 to we need to be able to do 12  crashes a day
 so his first design was  this
 contraption here that was literally  made out
 of baling wire and some plastic  tarps
 and some aluminum struts
 and stuff  but you could fix it in a
 few minutes so  in just a few months
 he had flown more  had more flights and more crashes
all the rest of the people in this prize  put together
 they started
 getting an  idea of what the problem actually was
and
 less than six months after Paul took
that drive across the Arizona desert  with his family they
 won the Cramer  prize it was easy
 just easy
and
 much more impressive than that
  was the second Kramer prize which
 is  flying from London to across
 the English  Channel and he won that a year later
 one  of the most thrilling videos you
ever see is called the gossamer  albatross you
 can order it every child  should see it
 it's one of the great  romantic videos
 of our time it's done  beautifully
 but so this was a
mile-and-a-half  on land and this was 22
 miles over water
and when asked about it
  Paul said well everybody else was
 trying  to make an airplane
 he
 said we were  trying to do a human
 powered flight so
he didn't start off with an airplane as  the idea and
 started off with the fact  that we had a third of a horsepower
 at  max to
 run this thing and we had to do  this and that and the
 other thing we had  to find out what that meant and that  wound up
extremely different than all of the  other things and
 bingo let's
 take a look  at one
 way of looking at this
 so here's  the effort and
 we can think of reward  going
 up that way and there's
 kind of a  threshold there
so here's what tenure committees
 and NSF  loves
 they love problems you can do and
you know what they don't care whether  the problems are worthwhile or not
  because Congress doesn't give a damn and  can't
 understand the difference between  any and Congress oversees NSF
 I'm on I  can say this because I'm on to several  of
 the NSF advisory committees but  basically if
 you want to get an NSF  grant you
 don't write it for science you  write it as an engineering project here  is
 how we're going to do it here's where  we're going to be successful this is
 why  almost nothing funded by NSF over the  last twenty
 years has been interesting  just hasn't been and
 these big  inventions that we use today we're not  funded
 by NSF at all they were funded by  our PI
 so
 the first thing we have to get  rid of is this
 idea of looking for the  keys under the lamppost
 which is not  where we've lost them
 all right
  so
 you can think of there being a curved
  something like this that you put effort
  in if you're lucky
 it might have a peak  like that and
 the McCready principle is  spend
 a lot of time finding
 that tiny  little place there
 it's just above the  threshold
 of being interesting but
way above the threshold of being  interesting so
 you're looking for the  minimum
 thing that you can do that's  qualitatively
 better and most
 good  problem solvers are incredible at this  they have
 a homing instinct McCready  would spend a
 long time thinking about  where he should put 80% of his
 effort  before he did a darn thing and he
 never  had a failure and he solved an enormous
number of problems in his lifetime just  because he worried about
 this because  this is where you learn about
 what you  need to know to do the real deal
and
 as soon as you get to that doable  thing you've
 actually changed this curve  and you
 brought the thing you wanted to  do into
 range and all of a sudden you've  got
 to break through so most of these  things are kind of two
 stages effects  the hardest thing is to get the
 funders  to pay for that first stage because
 it's  not cosmic so one of the reasons
 AI  research has not done very well the last  25
 years or so is because the new are
  Pro DARPA is not interested in funding  actual
 progress towards AI they're only  interested
 in funding the robot  combatant of the
 future something that  nobody knows how
 to do but they can sell  that to Congress
 and nobody can
so
 here's a couple of punchlines Susan
  Sontag I love this one
 all understanding  begins with our not accepting
 the world  as it appears this
 is the hardest one  this is where
 you have to do with this  exercise I do
 it every day literally not  getting
 normal considered harmful  because
 of course we have a zillion  mechanisms we don't want
 to have to  think every time you take a step right
so you can cripple yourself by  questioning everything
 that you do yet  so you but on the other hand every
 once  in a while you know take
 fifteen minutes  and instead of doing meditation on a  flower
 which is also a good thing  meditate
 on all the assumptions you're  making about the
 world that you're just  taking for granted for efficiency
  reasons and try and think of which ones
where the world would be very different  if you made different assumptions
 the
  reason even people who are good at this  stuff
 have to do it is because we all  have the same brains
 our brains are  defective nature didn't
 make those  brains for doing great inventions it
made those great brains for survival and  coping
 so we have to get around our  brain
 science of course is one of the  great ways of getting around human  brains that's
 what it was designed to do  but individually
 we have to get around  what's wrong with our brains
 so it's  best if we think of ourselves as
actually being unsane and that we're  dynamically
 trying to be stable with  respect to all
 that stuff out there Red  Queen said to
 Alex to Alice  try to understand three
 impossible  things before breakfast
 we have a blind  spot in our
 eye which if I had many
audiences I do this with I get prove  this to the audience
 by having them do  the experiment where
 a dot this big on  the paper will
before your eyes and be filled in by  your brain
 by material gathered from the  surrounding stuff
 because there's big  area in our retina that just doesn't  have
 any  optical
 neurons and
 it's
 the realization  that we have that blind spot in our  brain is
 filling in that helps us be  saner
 and I guess the one
 to leave you  with is this idea that if you realize  you're in
 the pink plane then you have a  chance of escaping
 it but if you think  the pink plane is all there is there
will be no thought of escape because how  can you escape all
 that there is thank  you very much
- any questions
 comments yes
well I you
 know it's
 so you get old they  give you
 gold medals and the proper  response to
 getting a gold medal is to  thank the funders because
 they just gave  you gold back before
 you turn the gold  medal so a good funder
 who is willing to  back
 something without trying to  rationalize
 it as well as the scientist  is going
 to do is the most critical
  thing in our field because it
 takes  money like I said in
 the old way that  Buck Rogers was this guy who lived in
25th century so the old saying was no  bucks no Buck
 Rogers and so what changed
in the 70s the thing that forces the arc  spark to come into
 existence was the  great ARPA funding of the
 60s was put  out of business by Congress because of  the Vietnam
 War it was no longer  possible to
 do that stuff in  universities funded that way so
 Taylor  decided to take one more shot
 at this  and convinced Xerox to fund about
 two  dozen of us to finish
dream of personal computing and  pervasive
 networks so that's the way  that worked and
 the funding has not been  good since
 1980 there's a lot
 of money  out there but the money is tied to
 the  perceptions of the funders as to whether  you're doing something
 worthwhile or not  and that is missing the point
  the real way ARPA did it was to
 say hey  we're willing to tolerate 60%
 failure if  everybody is working on
 really important  stuff because that 40% is going to
  change the world so this is a baseball  model
 we're not going to fire you if you  don't bat a thousand
 now if you bat
 368  like Ty Cobb did that's good
 so that's  the way they did it and back
 in the Cold  War Congress didn't over over C
 ARPA the  way they do now is the Vietnam
changed every  and not
 for the better their so that's  the simplest explanation and
 what but  once this thing winds down
getting all of these factors that I was  showing it's our tendency
comfortable  it's
 our tendency to say hey if
 I can  buy a compiler I'm
 not going to make one  even though that compiler might
back some thinking I need to do about  programming languages because
compiler I get I'm only going to compile  the thing kinds of
willing to compile it already has a  conception of
 what it's trying to do and  that's going to
 tie me to past  conceptions and I might have a good
 idea  so Park literally built
 every bit in  every atom of
 all of its computing  machinery
 build all the hardware and all  the software and it wasn't
 you know it  was a lot of work but we realized
it was we thought it would be a better  trade off if we could pull
