An Evening with Frank Warren

Frank Warren, the guy behind PostSecret, visited Ann Arbor on Friday. He travels and gives talks on PostSecret, and having followed that blog for over two years now, I thought I would go and listen to him speak.

This is the first time I've been to any sort of ticketed event. I've never been to concerts (except free ones), or improv theaters (at least not by myself).

If people are not familiar with PostSecret, it's an online social art project. People from all over the world send postcards to Frank. Sometimes the postcards are hand made, other times they're bought, but they share one feature: the sender has written a secret on the postcard. Frank then chooses 20 or so each week (he gets hundreds) to put on the blog, as well as some email responses people have had.

For his talks, he spends some time talking about the origins of the project, then sharing some secrets which were never posted or published in his books, and talks more about the appeal of human connection. At the end, people from the audience are encouraged to share their secrets on the spot.

Personally, I thought the two hours spent was well spent, although the event overall could be better. Although I applaud Frank from coming up with the idea, when people read PostSecret it's really for what people have poured their heart out on. The catharsis is from reading the secrets, and knowing that other people have the same thoughts, feelings, and fears that you do. Knowing that, I wish Frank would have allotted more time for the audience to contribute, to build the conversation in the moment, as opposed to talking about how PostSecret came to be. He's not a bad speaker - he has done this hundreds of times before, and gets the audience to laugh when he wants them to - but it's also missing the heart of why his project is so successful.

Nothing that Frank said had much affect on me. I was more affected by a secret that someone in the audience shared, which made me feel warm and euphoric, as though I had been drinking. It was a girl, who told the story of answering the phone one day and talking to the stranger on the other end for hours. At the end, as they were about to hang up, the stranger told her, "thankyou for talking to me. I was going to kill myself before I dialed a random number..." While telling the story, the girl's voice cracked and started sobbing, no doubt reliving the powerful effect that experience had on her. As Frank pointed out, people are just looking for someone to listen, to show that they care.

Since I haven't had a complete post on PostSecret before, I thought I would also share some of the secrets which resonated with me from the blog. My old dorm did do a similar event, and you can read some of what my (really) immediate neighbors wrote. These are from the official site:
  • "I want to tell you that i love you, but I'm afraid of the silence that might follow."
  • "I am afraid that the person I would love and myself will never meet, since we would both be too introverted to introduce ourselves."
  • "Today I realized I could no longer remember what you were like when you still loved me."
  • "I am a virgin. I've had three girls offer me free, easy, no-commitment sex. But I turned them all down, because I'm in love with a beautiful girl who just wants to be friends."
These next two were displayed in the same post. I thought it showed something about humans and love.
  • "I lost my virginity last night to a boy who doesn't love me... And all I care about is how I'm going to have to lie to people when they ask me if I'm still a virgin."
  • "You thought you lost your /virginity/ that night. I never had the heart to tell you... /It was only my hand/."
This one I thought a little strange, because it implied that love doesn't require respect:
  • "I love my wife, but I don't respect her, because she's not very smart."
Some more:
  • "Whenever a stranger stands by me, or passes, I wonder what's on their mind and when they walk away, I secretly miss them."
  • "Everywhere I look people have found someone to share their lives with. I don't think anyone is looking for me."
I do this too, and more than just near Valentine's:
  • "Every Valentine's Day, I go to Papyrus to rip off their card ideas."
And even more:
  • "I didn't take your virginity because I felt it was going to end and I love you so much I wanted it to be special for you."
  • "If I could go back in time, I'd go back to all the times we almost kissed... and I'd kiss you."
  • "I have pretended to be happy for so long. I don't know if I'm still pretending."
  • "I love you and I know you are going to hurt me. I resent that you will hurt me, but I don't know what to do."
  • "The best decision I ever made was letting you love me."
And my personal favorite:
  • "We accept the love we think we deserve."

Challenges

This has been a hard week for me.

On Tuesday I got back my midterm for intro to AI. The material for the course is mostly stuff I'd already done before, so Ive never been too worried about my grade. And, seeing that I got 85% on the midterm, I was correct. What had an undercurrent of an effect on me, which I didn't feel until that evening, was that my score was below both the mean and the average.

And all of a sudden, I started questioning myself. Am I really cut out to be in grad school? Can I make the original contributions that are required of me?

Then there's the anxiety of not knowing how I did in my machine learning midterm last week. Although I have taken a machine learning course before, this course is much more statistically oriented. While I am not completely clueless about statistics, the only course I took on it was in my junior year. I was definitely not up to scratch with my probabilities and density/mass functions, and it was a struggle to understand what the class was about.

It's strange, because I imagine that's how some people must feel even in high school. For people who are not particularly gifted at math, or science, or whatever subject, being required to take those courses must have been difficult for them. I have never had that problem - most of the courses I took even in college came easily to me, and very rarely did I really have to push myself to even get by in a class. With the combination of machine learning, and being below average in AI, I got a glimpse of what school must have felt like for some people.

Last summer when I first worked at CTY, one of the things which struck me the most during orientation was something not about me or the staff, but about the kids. Someone who has worked at CTY for many years commented that while the kids can do a lot of things by themselves, at some point when they get older they /have/ to work with each other, because what they're doing is simply beyond the capability of any single person. I remembered that comment, and even put it in my journal, because I wondered if that was the case for me too. Just as before CTY the students might not have needed to work together, and therefore have poor teamwork skills, I could phrase my own life in those terms. Everything up to and including college had a fixed upper boundary on what you could do. In elementary school you had to master multiplication, in high school it was calculus, and in college some selected topics within a certain field. I was smart, so I did all this without problems, but I wasn't smart enough to skip all the way to college or grad school before my age.

But once college ends, the world is wide open. In grad school and in research, the things you are learning may not have an agreed upon answer. The question might not even have been asked. Each professor that you deal with personally have expertise, and what they studied might not even have occurred to you. It is exciting for the same reason, but it also meant that things will not come easily anymore. The material is more recent - no longer are we studying the creation of some guy in the renaissance (calculus), but concepts and algorithms developed in the last 50 years, maybe even the last 10 years.

I was just suddenly overwhelmed by all of this, and wondered if I really would make my mark among all these giants.

The feeling passed by Wednesday afternoon, but the advice remains: pull yourself together, Justin.

A Little Mathematical Proof

Did you know that if you take any non-negative integer, then subtract the sum of its digits, the answer will always be divisible by 9?

For example, today's date is 11/06. 1106-(1+1+6) = 1098, and 1098/9 = 122.

Curious why? Here's a more general proof [pdf], that the difference between a number and the sum of its digits (if written in base b) will always be divisible by (b-1).

Michigan Updates

Alright, I've finally decided to sit down and write in more detail about my Michigan experience.

Living in Ann Arbor is a little strange to me, as it's the first time I'm further removed from a large city. Being in Chicago for four years, visiting San Francisco, LA, and Seattle during the summers, have gotten me used to there being interesting "cultural" events around. I put cultural in quotes because there is of course an Ann Arbor culture, but what I'm talking about is museums and history and architecture. Seattle and San Francisco were great in this respect, where as Ann Arbor is a college town, and thus is dominated by eateries. The university and the town developed together, so only a few blocks from campus the streets become much quieter, and within 15 minutes drive it quickly turns into farmland. Although Detroit is only an hour or so away, I know of no quick/cheap way to get there, and even then I doubt there's much that would interest me. As a result most of my free time is spent reading or climbing, which is a saving grace of sorts. Michigan has a bouldering wall on South Campus, which is across the city from where I live, and so I commute there at least twice a week. It is also one of the few ways I've met people outside of engineering, as North Campus is dominated by engineers. So I've gotten a bit better at bouldering.

As for classes, I'm taking three, and I'll go through them below. As a final though, I will talk about my experience as a Graduate Student Instructor (TA)

Introduction to AI

I've already done a lot of the things on the syllabus, such as search algorithms, inference, and Bayesian networks. All this stuff, however, was done in different classes, and I later decided that this is because a Michigan semester is longer than the Northwestern quarter. I think I could have gotten an equivalency for the course if I wanted to, but I'm considering doing research with the professor, and it has been a while since I did most of the Good Old Fashioned AI (GOFAI) stuff, so I might as well sit in. So far the course has not been surprising, and I'm rather glad I'm in it, as it's my single "easy" class for the semester.

Machine Learning

Although I've also taken a machine learning course before, my previous work was very implementation biased. This course, on the other hand, is based entirely on statistics and linear algebra. I've only taken one course in both subjects, and linear algebra in my freshman year. The good thing is that I've been teaching linear algebra through the years (as it is part of the course I peer tutor), so the knowledge I retained from that is very helpful. To be honest, I'm not sure I will find the mathematical background to these methods helpful. I did read a paper where principal component analysis was used before the course covered it, so it was exciting to know a concrete example.

Computational Complexity

My background for this course is even stranger. Michigan has an undergraduate course on the theory of computation, which I have obviously never taken. Northwestern used to have a similar course, but the only place I've found it referenced was in the course catalog. So most of what I know about Turing Machines come from recreational reading. And it turns out that it was enough: books on Turing and Godel, together with what I picked up in my programming languages and compiler courses, gave me enough background to take the course. I like the course a lot; the professor has a nice way of putting everything in narrative and historical perspective. If I wasn't so interested in AI, theory would definitely be an area I would look into. A system of logic is just so... elegant.

Graduate Student Instructor (for Programming and Intro Data Structures)

Ah, teaching. I'm always surprised by how much teaching I've done already. I was involved with the GSW for all four years, one of them as a student. And I've done two summers of CTY. Still, I expected doing discussion sections and office hours to be different. But it wasn't; after the first day, when I think back to see what I could improve, I didn't see anything that I needed to adapt to the new format. Actually, this is now not entirely true - I think I need to do a better job of emphasizing why these concepts are important, in the world of computer science. It's much harder to keep a room of 30 college students than a room of 14 6th graders engaged, especially when you don't have much flexibility on what to teach.

Anyway, I'm definitely enjoying being a GSI. At least one student have told me that what I do is helpful, and several others have been asking me questions on computer science concepts outside of the course. Yeah. Now the hard part: keeping it up.

Spiral Staircases

The new Computer Science and Engineering building has a nice spiral staircase that rises prominently from the main hall. It connects all four floors of the building, and is the most convenient way to get directly up; there is at least one other staircase (probably more; I haven't found any emergency staircases), but that has significant horizontal translation.

I thought a spiral staircase was pretty cool when I first saw it, but as I'm using it more often, I realized how stupid an idea it really is.

The problem with a spiral staircase is that the steps are non-uniform. Since people's gait depends on their height, and their height is a random variable, people have preferences as to how wide a step should be. With a circular staircase, the steps are obviously longer towards the outside and shorter towards the inside. This means people can pick where they walk, right? Except, of course, when there's two way traffic, so people are forced to one side of the staircase. With normal stairs, moving to one side doesn't change your gait, and so you can continue walking. With spiral staircases though, you have to constantly adjust how far you're stretching your legs just to keep going.

Besides that, Michigan is going well. By virtue of it being a public university, the classes are quite a bit bigger than those at Northwestern, even for relatively obscure classes like machine learning. I think that's the only reason why professors seem a little more distant here than at NU. On the other hand, I have two discussion sections to lead next week, as well as however many office hours, and this is also with the largest number of students I've dealt with yet. It'll be fun.

Writing About Writing

I have been writing recreationally for a while - I've been writing in my journal for close to 7.5 years, and this blog has been going for 2 years as well. Before that, I used to have a LiveJournal account, which was mostly used to keep my high school friends up to date with what I was doing. This blog stands out though, because it can be said that I'm doing a lot for a very small audience.

I recently read Paul Graham's essay on essays though, and I found it interesting that the word "essay" comes from the French verb/noun essayer/essai, meaning to try/an attempt. A lot of my blog posts are planned before hand. I have a running list of topics I want to write about, and while I find the time and mood to write them, I collect ideas and quotes in bullet-point form. Often times I don't actually know what I want to write, just want I want to write about. For example, I knew that I would do a post on The Fountainhead, but I didn't know what I want to say about it. Even for this short post, I'm not sure what my final point is, if I have one. Writing, then, is a way for me to figure out my own ideas. It's not just a tool for me to express my ideas to other people, but also for my ideas to become clearer in my head.

My friend Genia also wrote something about writing a little while back.

I thought it would be interesting to show the notes I have collected before writing this too. They're below:

Do Schools Kill Creativity?

I just watched this, and despite wanting to be the "whole purpose of public education throughout the world" that is the university professor, I have to agree with him.

The TED talk can be found here:
http://www.ted.com/talks/ken_robinson_says_schools_kill_creativity.html

I'm also putting the transcript up, if reading is more your thing.

Do Schools Kill Creativity?
Ken Robinson


Good morning. How are you? It's been great, hasn't it? I've been blown away by the whole thing. In fact, I'm leaving. There have been three themes, haven't there, running through the conference, which are relevant to what I want to talk about. One is the extraordinary evidence of human creativity in all of the presentations that we've had and in all of the people here. Just the variety of it and the range of it. The second is that it's put us in a place where we have no idea what's going to happen, in terms of the future. No idea how this may play out.

I have an interest in education -- actually, what I find is everybody has an interest in education. Don't you? I find this very interesting. If you're at a dinner party, and you say you work in education -- actually, you're not often at dinner parties, frankly, if you work in education. You're not asked. And you're never asked back, curiously. That's strange to me. But if you are, and you say to somebody, you know, they say, "What do you do?" and you say you work in education, you can see the blood run from their face. They're like, "Oh my God," you know, "Why me? My one night out all week." But if you ask about their education, they pin you to the wall. Because it's one of those things that goes deep with people, am I right? Like religion, and money and other things. I have a big interest in education, and I think we all do. We have a huge vested interest in it, partly because it's education that's meant to take us into this future that we can't grasp. If you think of it, children starting school this year will be retiring in 2065. Nobody has a clue -- despite all the expertise that's been on parade for the past four days -- what the world will look like in five years' time. And yet we're meant to be educating them for it. So the unpredictability, I think, is extraordinary.

And the third part of this is that we've all agreed, nonetheless, on the really extraordinary capacities that children have -- their capacities for innovation. I mean, Sirena last night was a marvel, wasn't she? Just seeing what she could do. And she's exceptional, but I think she's not, so to speak, exceptional in the whole of childhood. What you have there is a person of extraordinary dedication who found a talent. And my contention is, all kids have tremendous talents. And we squander them, pretty ruthlessly. So I want to talk about education and I want to talk about creativity. My contention is that creativity now is as important in education as literacy, and we should treat it with the same status. Thank you. That was it, by the way. Thank you very much. So, 15 minutes left. Well, I was born -- no.

I heard a great story recently -- I love telling it -- of a little girl who was in a drawing lesson. She was six and she was at the back, drawing, and the teacher said this little girl hardly ever paid attention, and in this drawing lesson she did. The teacher was fascinated and she went over to her and she said, "What are you drawing?" And the girl said, "I'm drawing a picture of God." And the teacher said, "But nobody knows what God looks like." And the girl said, "They will in a minute."

When my son was four in England -- actually he was four everywhere, to be honest. If we're being strict about it, wherever he went, he was four that year. He was in the Nativity play. Do you remember the story? No, it was big. It was a big story. Mel Gibson did the sequel. You may have seen it: "Nativity II." But James got the part of Joseph, which we were thrilled about. We considered this to be one of the lead parts. We had the place crammed full of agents in T-shirts: "James Robinson IS Joseph!" He didn't have to speak, but you know the bit where the three kings come in. They come in bearing gifts, and they bring gold, frankincense and myrhh. This really happened. We were sitting there and I think they just went out of sequence, because we talked to the little boy afterward and we said, "You OK with that?" And he said, "Yeah, why, was that wrong?" They just switched, that was it. Anyway, the three boys came in, four-year-olds with tea towels on their heads, and they put these boxes down, and the first boy said, "I bring you gold." And the second boy said, "I bring you myrhh." And the third boy said, "Frank sent this."

What these things have in common is that kids will take a chance. If they don't know, they'll have a go. Am I right? They're not frightened of being wrong. Now, I don't mean to say that being wrong is the same thing as being creative. What we do know is, if you're not prepared to be wrong, you'll never come up with anything original. If you're not prepared to be wrong. And by the time they get to be adults, most kids have lost that capacity. They have become frightened of being wrong. And we run our companies like this, by the way. We stigmatize mistakes. And we're now running national education systems where mistakes are the worst thing you can make. And the result is that we are educating people out of their creative capacities. Picasso once said this: he said that all children are born artists. The problem is to remain an artist as we grow up. I believe this passionately: that we don't grow into creativity, we grow out of it. Or rather, we get educated out if it. So why is this?

I lived in Stratford-on-Avon until about five years ago. In fact, we moved from Stratford to Los Angeles. So you can imagine what a seamless transition that was. Actually, we lived in a place called Snitterfield, just outside Stratford, which is where Shakespeare's father was born. Are you struck by a new thought? I was. You don't think of Shakespeare having a father, do you? Do you? Because you don't think of Shakespeare being a child, do you? Shakespeare being seven? I never thought of it. I mean, he was seven at some point. He was in somebody's English class, wasn't he? How annoying would that be? "Must try harder." Being sent to bed by his dad, you know, to Shakespeare, "Go to bed, now," to William Shakespeare, "and put the pencil down. And stop speaking like that. It's confusing everybody."

Anyway, we moved from Stratford to Los Angeles, and I just want to say a word about the transition, actually. My son didn't want to come. I've got two kids. He's 21 now; my daughter's 16. He didn't want to come to Los Angeles. He loved it, but he had a girlfriend in England. This was the love of his life, Sarah. He'd known her for a month. Mind you, they'd had their fourth anniversary, because it's a long time when you're 16. Anyway, he was really upset on the plane, and he said, "I'll never find another girl like Sarah." And we were rather pleased about that, frankly, because she was the main reason we were leaving the country.

But something strikes you when you move to America and when you travel around the world: every education system on earth has the same hierarchy of subjects. Every one. Doesn't matter where you go. You'd think it would be otherwise, but it isn't. At the top are mathematics and languages, then the humanities, and the bottom are the arts. Everywhere on Earth. And in pretty much every system too, there's a hierarchy within the arts. Art and music are normally given a higher status in schools than drama and dance. There isn't an education system on the planet that teaches dance every day to children the way we teach them mathematics. Why? Why not? I think this is rather important. I think math is very important, but so is dance. Children dance all the time if they're allowed to, we all do. We all have bodies, don't we? Did I miss a meeting? Truthfully, what happens is, as children grow up, we start to educate them progressively from the waist up. And then we focus on their heads. And slightly to one side.

If you were to visit education, as an alien, and say "What's it for, public education?" I think you'd have to conclude -- if you look at the output, who really succeeds by this, who does everything that they should, who gets all the brownie points, who are the winners -- I think you'd have to conclude the whole purpose of public education throughout the world is to produce university professors. Isn't it? They're the people who come out the top. And I used to be one, so there. And I like university professors, but you know, we shouldn't hold them up as the high-water mark of all human achievement. They're just a form of life, another form of life. But they're rather curious, and I say this out of affection for them. There's something curious about professors in my experience -- not all of them, but typically -- they live in their heads. They live up there, and slightly to one side. They're disembodied, you know, in a kind of literal way. They look upon their body as a form of transport for their heads, don't they? It's a way of getting their head to meetings. If you want real evidence of out-of-body experiences, by the way, get yourself along to a residential conference of senior academics, and pop into the discotheque on the final night. And there you will see it, grown men and women writhing uncontrollably, off the beat, waiting until it ends so they can go home and write a paper about it.

Now our education system is predicated on the idea of academic ability. And there's a reason. The whole system was invented -- around the world, there were no public systems of education, really, before the 19th century. They all came into being to meet the needs of industrialism. So the hierarchy is rooted on two ideas. Number one, that the most useful subjects for work are at the top. So you were probably steered benignly away from things at school when you were a kid, things you liked, on the grounds that you would never get a job doing that. Is that right? Don't do music, you're not going to be a musician; don't do art, you won't be an artist. Benign advice -- now, profoundly mistaken. The whole world is engulfed in a revolution. And the second is academic ability, which has really come to dominate our view of intelligence, because the universities designed the system in their image. If you think of it, the whole system of public education around the world is a protracted process of university entrance. And the consequence is that many highly talented, brilliant, creative people think they're not, because the thing they were good at at school wasn't valued, or was actually stigmatized. And I think we can't afford to go on that way.

In the next 30 years, according to UNESCO, more people worldwide will be graduating through education than since the beginning of history. More people, and it's the combination of all the things we've talked about -- technology and its transformation effect on work, and demography and the huge explosion in population. Suddenly, degrees aren't worth anything. Isn't that true? When I was a student, if you had a degree, you had a job. If you didn't have a job it's because you didn't want one. And I didn't want one, frankly. But now kids with degrees are often heading home to carry on playing video games, because you need an MA where the previous job required a BA, and now you need a PhD for the other. It's a process of academic inflation. And it indicates the whole structure of education is shifting beneath our feet. We need to radically rethink our view of intelligence.

We know three things about intelligence. One, it's diverse. We think about the world in all the ways that we experience it. We think visually, we think in sound, we think kinesthetically. We think in abstract terms, we think in movement. Secondly, intelligence is dynamic. If you look at the interactions of a human brain, as we heard yesterday from a number of presentations, intelligence is wonderfully interactive. The brain isn't divided into compartments. In fact, creativity -- which I define as the process of having original ideas that have value -- more often than not comes about through the interaction of different disciplinary ways of seeing things.

The brain is intentionally -- by the way, there's a shaft of nerves that joins the two halves of the brain brain called the corpus callosum. It's thicker in women. Following off from Helen yesterday, I think this is probably why women are better at multi-tasking. Because you are, aren't you? There's a raft of research, but I know it from my personal life. If my wife is cooking a meal at home -- which is not often, thankfully. But you know, she's doing -- no, she's good at some things -- but if she's cooking, you know, she's dealing with people on the phone, she's talking to the kids, she's painting the ceiling, she's doing open-heart surgery over here. If I'm cooking, the door is shut, the kids are out, the phone's on the hook, if she comes in I get annoyed. I say, "Terry, please, I'm trying to fry an egg in here. Give me a break." Actually, you know that old philosophical thing, if a tree falls in the forest and nobody hears it, did it happen? Remember that old chestnut? I saw a great t-shirt really recently which said, "If a man speaks his mind in a forest, and no woman hears him, is he still wrong?"

And the third thing about intelligence is, it's distinct. I'm doing a new book at the moment called "Epiphany," which is based on a series of interviews with people about how they discovered their talent. I'm fascinated by how people got to be there. It's really prompted by a conversation I had with a wonderful woman who maybe most people have never heard of, she's called Gillian Lynne, have you heard of her? Some have. She's a choreographer and everybody knows her work. She did "Cats," and "Phantom of the Opera." She's wonderful. I used to be on the board of the Royal Ballet, in England, as you can see. Anyway, Gillian and I had lunch one day and I said, "Gillian, how'd you get to be a dancer?" And she said it was interesting, when she was at school, she was really hopeless. And the school, in the '30s, wrote to her parents and said, "We think Gillian has a learning disorder." She couldn't concentrate, she was fidgeting. I think now they'd say she had ADHD. Wouldn't you? But this was the 1930s, and ADHD hadn't been invented at this point. It wasn't an available condition. People weren't aware they could have that.

Anyway, she went to see this specialist. So, this oak-paneled room And she was there with her mother, and she was led and sat on a chair at the end, and she sat on her hands for 20 minutes while this man talked to her mother about all the problems Gillian was having at school. And at the end of it -- because she was disturbing people, her homework was always late, and so on, little kid of eight -- in the end, the doctor went and sat next to Gillian and said, "Gillian, I've listened to all these things that your mother's told me, and I need to speak to her privately." He said, "Wait here, we'll be back, we won't be very long." and they went and left her. But as they went out the room, he turned on the radio that was sitting on his desk. And when they got out the room, he said to her mother, "Just stand and watch her." And the minute they left the room, she said, she was on her feet, moving to the music. And they watched for a few minutes and he turned to her mother and said, "Mrs. Lynne, Gillian isn't sick, she's a dancer. Take her to a dance school."

I said, "What happened?" She said, "She did. I can't tell you how wonderful it was. We walked in this room and it was full of people like me. People who couldn't sit still. People who had to move to think." Who had to move to think. They did ballet, they did tap, they did jazz, they did modern, they did contemporary. She was eventually auditioned for the Royal Ballet School, she became a soloist, she had a wonderful career at the Royal Ballet. She eventually graduated from the Royal Ballet School and founded her own company, the Gillian Lynne Dance Company, met Andrew Lloyd Weber. She's been responsible for some of the most successful musical theater productions in history, she's given pleasure to millions, and she's a multi-millionaire. Somebody else might have put her on medication and told her to calm down.

Now, I think -- What I think it comes to is this: Al Gore spoke the other night about ecology, and the revolution that was triggered by Rachel Carson. I believe our only hope for the future is to adopt a new conception of human ecology, one in which we start to reconstitute our conception of the richness of human capacity. Our education system has mined our minds in the way that we strip-mine the earth: for a particular commodity. And for the future, it won't serve us. We have to rethink the fundamental principles on which we're educating our children. There was a wonderful quote by Jonas Salk, who said, "If all the insects were to disappear from the earth, within 50 years all life on Earth would end. If all human beings disappeared from the earth, within 50 years all forms of life would flourish." And he's right.

What TED celebrates is the gift of the human imagination. We have to be careful now that we use this gift wisely, and that we avert some of the scenarios scenarios that we've talked about. And the only way we'll do it is by seeing our creative capacities for the richness they are, and seeing our children for the hope that they are. And our task is to educate their whole being, so they can face this future. By the way -- we may not see this future, but they will. And our job is to help them make something of it. Thank you very much.
