Kwabena Boahen: Making a computer that works like the brain

[PeopleBreeze]

Information is the access gate to liberty, depending on how it is used it can help save or destroy a life. In this talk Kwabena Boahen is demonstrating the differences between computer chips and the brain pertaining to how they function. peoplebreeze com

[PeopleBreeze]

This is the result we get when we expose Africa to technology, we create people like Kwabena along with others who have the ability to make computer chips behave more like the human mind which can in the future be implemented to save a life. peoplebreeze com

[lamuziq]

Neuroscience and Cosmology are both at the consequence of theories; neither have ultimate physical data. You cannot examine a stars core as it turns to iron before supernova. You cannot examine a thought processes forming, ideas being flourished, creativity and emotions being nurtured and engaged. We cannot see the formation of these events, only electric signals and heat signatures of the effects. IE; the map is NOT the territory . The ink / paper is "not" the chicken soup recipe.

[lamuziq]

Meet the forgotten 90 percent of your brain: glial cells, which outnumber your neurons ten to one. And no one really knows what they do. To quote Carl Zimmer. - Yet, we have videos like this implying that we can make a computer that functions like the brain (ie; we understand the brain enough to emulate it) and it's intellectually dishonest.

[lamuziq]

Well at least we aren't teaching our kids science fiction! Oh....Wait. Yes we are. No mention of glia, no mention of map is not the territory, no mention of our inability to have a consensus in neuroscience due to all the dark matter between our ears, et cetera. This is one of those lectures that history will laugh at. In 50 years we'll be looking at early 21st century neuroscience like it was written in crayon by an infant. I salute his effort, but this Ted is a vain exercise for humanity.

[mideastatheist]

""""not enough africa in them""" he meant human revolution........ it is believed that the climate of Africa is the responsible for evolution of human brain and essentially intelligence ...

[xaiomanga]

Aren't there a lot of economic limitations to the advancement of information-processing technology?

[Shadowstray]

I wonder where he found a laptop running on 10W. The more efficient netbooks work in the 10-15W range :P

[farlincomcom]

@Shadowstray

I think he meant only the processor

[donniedarkodevotte]

I hope everyone is prepared for the on-coming robot apocalypse. Once they become self-aware and realize how horrible a species we are to our environment and ourselves, we're getting rebooted.

[AroundSun]

woah his brain is huge

[Martintheess]

make cameras that works like eyes too :D

[BeAsTm0aD]

I think what's different is that in a brain, every little neuron is essentially it's own little brain / thinking machine, to some extent. Computers just send data without any smaller degree of process within this process, would anybody agree with this?

[AlgeKalipso]

@BeAsTm0aD Wouldn't this create an infinite regress, where the actual thinking could not be located anywhere? The way neurons work is already well understood, and it is pretty mechanical. People like Kwabena Boahen would agree that the neuron is the functional unit of the brain.

[BeAsTm0aD]

@AlgeKalipso consciousness is still a mystery. Like the way we think is incredibly mind blowing - it takes billions of neurons to form a thought - where does that initiative come from to form a thought, or even a new creative thought for that matter? It is simple in that neurons are enticed to activate a memory through smell or any form like that, but to actually sit and move from thought to thought from one is like a series of jumps from all neurons cooperating - hard to say what's going on.

[BeAsTm0aD]

@AlgeKalipso it's almost like each neuron holds a piece to a puzzle and each piece can be made to fit into new places to form new complete puzzles

[Jddnd]

@BeAsTm0aD i was imagining something similar. ;)

[crudhousefull]

@BeAsTm0aD Very true (just in case you don't check back to see if you got some thumb ups)

[guerillachan20]

were losing the human connection the more we move towards computers the less time kids will be playing outdoors and then soon enough they won't know the difference between the physical world and the virtual world its sad.

[MrTanookiMario]

@guerillachan20

...he says while on the computer, enjoying the revolutionary way technology allows us to spread information. -_-;;

[ranasingh]

Basically aritfical intelligence, if you read up on artfical neural networks ANN you will see more of simulating neuron activity in computers but its already done in small applications I kinda agree PC should be going this way

[luisfcayo]

Halo O_O

[Matthew808x]

why do alot of techies where glasses?

im not trying to be dick but why do so much of them wear glasses?

[erratichippie]

techies wear glasses because they work with computers, and spending a lot of time in front of a monitor has been directly linked to developing poorer eyesight. especially myopia.

[Robstailey]

most likely because staring at screens all the time ruins your vision.

[Matthew808x]

@Matthew808x k thanks for the reply's. I hope no one took it in the wrong way and if i did offend anyone i apologize.

[killtheotherside]

they look at the computer 90% of their life.

[BeAsTm0aD]

@Matthew808x by staring at a computer screen, massive amounts of light are hitting your retinas and over time it weakens the muscles in the eye so they cannot readjust to distance - this is also the problem with schooling. There is too much close work and not enough looking into the distance. If anything, I think there should be classes where you go outside and observe the environment or something.

[elpresidio]

Kwabena Boahen is featured in October 2009 issue of Discover periodical.

[elpresidio]

Google Search "Brains in Silicon" the name of this program study at Stanford University in which he is involved with as principal investigator.

[cuallito]

what was the name of the intrument he showed at the end?

[RRRRussia]

anyway i think the idea that the current implementation of a computing system as seen in modern computers is very "brute force" and lacking elegance is an important idea to consider. i have been looking into some research on modeling the human brain as well. i believe that one day the difference between an organic nervous system like that in a human or fish and the system inside a computer or cell phone or whatever will be very ambiguous.

[Anon1696]

He just had to say aks during the presentation...

Smart man though.

[bentothetenthpower]

Right, because you have NO accent.

[Anon1696]

Aksent?

[bentothetenthpower]

Hehe aksent.... well played.

[GeorgeH1972]

don't forget africans invented the drum!

And why this guy keep on saying basically? At least his not repeating "you know what I'm saying"

[bradford5353]

Very interesting guy. What he is talking about is already about a 40 year thought process in the U.S., Russia, China and Europe. Where I worked Symtek we were working on organic chip environmental testing machines back in mid-80's. There are laws of physics that control what Mr. Boahen is speaking about that current technology is not able to fully overcome. Nano technology came about as a first step in solving the issues Mr. Boahen is speaking...but, we are not yet able to create life force.

[ashtray45]

I feel a little bad for him, it seems like hes saying that africans will invent Ai because they are african. I'm not racist in the slightest, I have lots of black friends. How africans are going to create a silicon brain capable of creativity? Why does he think AFRICANS will be the ones to do it? They havent been resposible for any technological advancements (yes for geological reasons and enviromental reasons), but it baffles me why he thinks that they will acheave the 'holy grail' of tech...

[marcsfutures]

I can see where you are coming from. Have you considered that there is another side to your interpretation?

Kwabena is honored to come from Africa to bring a different perspective that contributes a sense of oneness in technological evolution.

[boorens18]

when he referenced "not enough africa in them" he didnt mean literally african work, he was making a metaphor for easy going...fluid, the culture basically

[calumwl]

i find that really offensive, being african myself, i dont see why u think that we couldnt come up witht these kind of advancements. u are just being singleminded and think that america should be the country that comes up with these advancements

[ashtray45]

First of all I am not American nor am I saying anything about America, nor am I saying anything about the ability of black or African people. I am just saying that technology itself originated in Europe and North America, africans may have even helped.. I think he just worded the last part of his speech badly because i can feel the embarassment and confusion from the host and the audience.

[Radjehuty]

I also see that in the host as well and thought he was actually quite rude in a sense.

But I don't think he's saying that Africans will be THE ones to develop A.I. simply because they're Africans, but he was trying to express that different perspectives have something to contribute to knowledge. It seems feasible that maybe he was also trying to say that coming from a different culture was conducive having his gut reaction that this was the wrong way about it.

[ashtray45]

And one more reason I think is akward, its an EXTREMELY bold claim with NOTHING to back it up.

[srgrimm]

I didn't detect any awkwardness from him or the host....maybe I missed something. And what are you talking about when you talk about a bold claim with nothing to back it up. What claim is that?

[whizzydrawrapwrite]

@ashtray45 I think he backs it up...

[fosibodu]

You said, "They havent been resposible for any technological advancements". You are wrong. An african, specifically Nigerian, invented a formula that allowed computers make 3.1 billion calculations/second and broke the world record and won a Gordon Bell prize (Nobel prize in computing)

[whizzydrawrapwrite]

@ashtray45 doubtful, you are. Too much t.v. for you.

[TGGeko]

That is a really interesting way of computing. Today's computers get faster by making the bottleneck bigger, but it's still a bottle neck. Neural nets are trying to get this parallel processing.

[FugalQuease]

When I first used a computer & learned how it worked I had exactly the same reaction (in Australia in the 70s, so it's not uniquely african, but I get his point) & always expected that one day the CPU would be replaced with intelligent memory. In a way I'm still trying to make it happen (& I've used these neuromorphic chips & met Kwabena :) )

[donkekeli]

GENIUS... perspectives always matter in problem solving. One basic reason why diversity remains in various products, from cars to computer. Apple differs from PC.

[tux937534]

"I esteemed 10^16bits/s"

How did he esteem that the brain has roughly that computational capacity? I don't think that's something so banal, how did he do that?

[colordive]

Don't separate the brain and the computer. Have them become intertwined, using radio signals and nanobots. Right now the internet is sort of becoming a one mind type of network. It is becoming like another virtual world, that meshes with the real world. Cloud computing is another thing, with software and everything else, existing in the network and not on the computer itself.

[DVAFP]

everything that's "in the network" is actally in computers. The internet might seem an etheral space with a lot of information in it, but its actually just computers connected with each other. Youtube is just a program that is running in some servers somewhere, just like the google search engine and all the websites. But maybe you know something i dont.

[TGGeko]

Yes, but it is running on several servers all across the world. So, there is really no localization in the physical world. There is only such localization in the digital world. And if you think about it, that makes the internet more real in cyberspace than in the "real" world.

[agentas337]

the problem is that it will sort shotcut the pc because.... ok , lets face it its inposible

[threelegduck]

i feel like the commentator was a bit of an ass at the end. i know what he means - what does this have to do with africa? is there anything characteristically african about trying to build a neural network or a brain using transistors? ... other than the fact that you're from africa? we'll likely see in a decade or two from the students he trains and the failures and successes of the work. maybe africa characterizes his audacity, and stubbornness that it takes to do science

[sub7th]

I think what he was trying to say is that, coming from africa, he hadn't been educated on computers the way that some other countries are. For him it was more of an exploratory process, which helped him to see it from an outside perspective.

But the first quote, I belive, was more about the african environment than africans themselves. It's a very dynamic and adaptive environment and I belive Brian Eno was just commenting on the need for more of that in CPU's.

[27Morpheus]

Truth, it is a diverse (environmnetally) continent. It snows in africa btw.

It's funny that's mentioned, our species is thought to have originated in East Africa at a time when all hell (grasslands, jungles, mountains, cliffs, pits) was breaking loose in the Rift Valley. Further, the earliest evidence of our modern 'mind' [culture] occurred in Blombos cave, South Africa @ 100,000 years ago.

But this culture was introduced to Europe by 40 k years ago and we're all really justafrican anyway.

[threelegduck]

the money is in the software

[SiAz23]

They already have a replacement for silicon.

It's called the human brain (and other organic materials as mentioned by biotekslime). This presentation and others like it are preparing us for a machine-human interface. There have already been conferences on brainchipping the population, such as the one at loyola uni. This is about creating slaves, its not about helping any of us. If you retain critical thinking abilities, I urge you never to take an implant.

[duanemay]

how can you type with all that bong smoke blocking your keyboard?

[sanjay926]

not sure who you're talking to, but

I learned how to type without looking at my fingers.

how about something relevant to the video like: i think this idea is very interesting, shows how the vision of the future is usually wrong and always changing. my question is, what will we do and what are the practical uses and applications of powerful and thinking computers?

[LegendSaber]

Very interesting. If Moore's law is on this fellow's side, such machines could well be a reality in just a decade or less.

[amirdoit]

with the current technology we'll never be able to crate something like brain, to do that we have find out the alternative to silicon.

[Da5an4nThu9]

how about cuantum (propably not the right spelling) computers? i dont know alot about them just heard some science dude say that it will be  an alternative for silicon.

[tenaciousblck]

Possibly. Its called quantum computers. It the idea, that instead of storing data in bits, we should attempt to store in it in a more efficient quibit thereby streamline computer processing power even more. It goes into ideas of quantum physics of entanglement and superposition. Partly meaning matter exists in pairs and can exists in several physical locations at once. If you do something to one half of a matter pair, the other half, no matter where it is in universe, will exhibit the same chang

[fusrname]

I think the problem is the "programming". You can reproduce brains with computers today, a friend of me has just finished his thesis about a certain type of subsystem. The hard thing is to connect the different systems. By now they know quite exactly how the brain is built, but they do not understand the connections between the neurons fully. So you can build a brain if you figure that out, however, you're right with the current technology it will be a (ten)thousandth of the speed of the brain.

[DSBrekus]

In my opinion the most important part is making a more analog computer, simple yes/no is far from reality and could hardly ever be human in its thinking :P

[DanHipp]

lots of little yes's and no's emerge on a higher level of description as analog computation.

[eoinycroiny]

sounds very posibible to me, hope they figure it out befor my time's up

[bioteksublime]

Eluhn LOL...smart response but i gues i didn't explain my self properly.

The computers of 2015 will have molecular components qualifying them as organic

(or qualifying us as machines).

1. To adapt your enviroment you must first learn how it works,

odservation-imitation-modifica­tion, humans understand a great number of things nature does.

2. With organic computers it would be far easier to augment the human brain than make them sentient.

[ELuhn]

Boahen is definitely on the right track, emulating "organic" processes like vision directly in the hardware. But before AI, or even AL, can really take off, we need some way to quickly and cheaply design and manufacture circuitry that directly emulates these models, rather than stuffing everything into binary.

(Sorry for monopolizing comments, but 500 characters just isn't enough.)

[ELuhn]

What has made computers so successful as a tool, so far, is their fundamental stupidity. Regardless of what the application or process is, to the ALU it's all just 0s and 1s. We humans still do 99.999% of the work, taking complex, nonlinear processes like vision and trying to distill them into a symbology which a computer can "understand." If we can, then we can be fairly confident that we're on the right track ourselves.

[bioteksublime]

An archetect who could make blueprints (ideas, thought) based on its input,its enviroment.

Why try to predict and adapt to an enviroment when you can adapt your enviroment to you.

"attack is the best form of defence"

Give an AI a strong static blue print and it will obey to you no matter what happens.

[ELuhn]

Yes, but before you can adapt your environment, you have to understand it. You need to understand how something works first, before you can improve on it. Before true AI can happen, we have to make computers that can sense and respond to their environment the way living organisms do. *Then* we can address the question of how to make a computer "think."

[bioteksublime]

"Computers shouldn't be more like brains..

cuzz what if the get a mind of there own..."

LOL LOL godver you need to learn more about molecular engineering and neurology.

Only organisms that are adequatly adapted to there enviroment live.

Evolution had to go a step further when it came to dealing with constantly changing enviromnets. So it made the adaptive organism, an organism that could learn from its errors. Evolution had drawn out the static blueprint(genome)to making an archetect.

[bioteksublime]

science is science, god is.....

Well all you will ever know is its name.

[DaveODrisc]

Science is GOD!!

Man I love to think about all the mad shit we are gonna see!!

[SonicWolfen]

SonicWolfen's the name and making machinimas is my game you should check'm out ep 1 and 2 are a waste but yea the others are fun please....look at'm :)

[JohnDeBunkTest]

There is no reason that computers cannot become self aware. We have no "magical soul" just a mapping of our surroundings, the ability to interact, and capacity to learn.

Kwabena Boahen has shown us how computers can begin processing the information gained in vision into a mapping of our surroundings.

[asdf2000]

@JohnDeBunkTest

and you know this... how?

how can you possibly say there is no reason they can't become self aware when you don't know what it takes to be self aware ?

[bleuandie048]

i know this has nothing to do with anything he said at all but...WOOOO!!! ghana all tha way!

[godverdegodverdomme]

"but *if* it would, that suggests that today's computers are self aware to a very minor degree, or?"

No :}

Computers would have to be much more

complex, and differently aligned (internally).

Our average computer only processes external

input to calculate, and return results.

Very much like an overgrown pocket calculator.

[DruovanniDefoe]

Evolution at work.. Artificial Life iz tha next stage.. We'll soon understand that the brain iz all we need 2 function, everythin else is disposable..

[bioteksublime]

Kwabena mentioned that computers would be as detailed (good) as human brains by 2015.

CRN

Center for Responsible Nanotechnology claim that by 2015 scientists and engineers will have finally developed a molecular nanosystem (most probably a silicon one),

A new lifeform in other words.

Kwabana must be talking about the same thing.

P.S. CRN has a website BTW.

[bioteksublime]

The japanese have worked out how to compute with snthetic dna, using enzymes as the hard-drive and DNA as the information.

1 KILO OF DNA CAN CONTAIN ALL OF THE INFORMATION EVER PRODUCED, BY EVERY SINGLE CUMPUTER ON EARTH.

[MasterMark123]

I have a feeling that we're working toward something that will one day become self aware ... think of crossing that threshold .. would it then be artificial ? or real life ? reminiscent of H.A.L. in 2001 or of the terminator films eh ..

[bioteksublime]

We are going from big to small, its a bit weird that we're going back to are origins lol.

DNA is the only molecular nanosystem to exist on earth,a self replicating macro-molecule that is capable of trillions of customisations.

Each species being a different customisation, each race, each individual.

Ironic, to think that man is starting to use the technology that made him and what will come next.

[Bobstew68]

If self awareness comes from the complexity, that would mean it's a gradual thing. I'm not sure a computer that could operate in the same way as a brain *would* be self aware (yes, I'm keeping open the 'soul' idea), but *if* it would, that suggests that today's computers are self aware to a very minor degree, or?

[marsCubed]

To be self aware a computer would need to have, at the very least, some kind of abstract representation of itself at it's inputs which would form part of it's model of reality. this would be the basis for a feedback loop in which self could exist as action nexus and consequences. complexity would enrich the model. self awareness need not mean consciousness as we normally define it. it could be a calculator, it just isn't very likely that todays comps will give us satisfactory forms of this.

[SCX2k]

very interesting

perhaps a new step to artificial life?

[chyna98]

I'm not with that Xenophobic shit, but I love seeing black folks doing very well in life. I'm black American btw.

[bluekads]

Mr.Boahen, you are good in explaining

but what you are talking about needs alot of video's, to show us how these things work...

Thank you :)

[1schwererziehbar1]

great speaker!

btw i want to thank TEDtalksDirector for putting the videos up in high quality. uploading them at all is great enough and you are helping thousands of people to get more wide-minded. but in high quality! supercool!

[mfjeff]

haha i love his laugh

[b4skin]

The supposed drawbacks of computer 'answers' has also led to the change by which humans format the questions. (search engines anyone) The logical buffer by which they operate, though certainly more complicated by necessity of all possible relative routes to 'answers' is also a good "reason" why our own neuronet can be disruptive by making preordained distinctions not neccessarily applicable to the goal of the question. NOT that exploring the reasons doesn't hold merit, cuz I believe it does.

[swyft187]

He made no assumptions on African conceptuality as being superior as you seem to "presuppose" (see what I did there? :P), he just demonstrated the difference in perspective.

And a search engine isn't considered an answer to a question(query). It is nothing more then a reference to someone's answer to the question. Nevertheless, I might of misunderstood you since I fail to grasp your syntax. My apologies in advance.

[b4skin]

swyft187:in an example of you granting the possibily of misunderstanding the wording or intent of my post, i think even the advent of search engines has proposed the difference between how human thought can make inferences to queries which a computer 'may not get'. in science the articulation and definition of it's process is a distinct and important goal, such as is in computer programming.

[5uper5tring]

He has his basic nuero physiology wrong. Well as long as he has an expert advising him I suppose... sigh.

[LJPpro]

Lol, yeah right. Go fuck yourself omglol, please.

[samann95014]

great thinker!!! best respect to great african american thinkers!!

[b4skin]

Maybe instead of jumping on board, you could give 'best respect' to Kwabena Boahen, HIMSELF!

[PenguinBoy92]

yeah but it would be so awesome if jesus goes, hell yeah! me2 did u see this computer brain vid? was featured.. YEAH who the hell was that gay ass nigger?

[originaldna]

watch?v=AdhTHHyJDDQ

Make sure you watch all of it, then you will know who he is Stable albino.

[ShatteredValentine]

CHOCOLATE RAIN

[b4skin]

You spelled RAIN (REIGN) wrong.

[jflava1985]

this would be boring too the majority of my age group but it had my 100% attention very interesting

[blackberryjuice1]

I love how he tried to come in with that old tired condescending "how is your contribution to technology going to help the poor starving mentally slow African population" in the end. The truth is that the first civilizations were in Africa, not Iraq. Africa had 10X as many scripts while Europe had none. The entire world is impoverished when we continue these old tired racist memes of the past. Face it, all humans are geniuses, especially the African.

[hooah68]

wat

[jeremmorrow]

Excellent.

[wingeddanny]

Computers shouldn't be more like brains..

cuzz what if the get a mind of there own...

who knows what could happen lol just like the movie I-robot with will smith :P

[catapaultpenguin]

then will smith will save us

[wingeddanny]

Hahaha :P

[Mrmoc7]

Just like humans can kill humans, I'm sure we can find a way to blow up any computer that gets out of hand.

Problem solved.

[godverdegodverdomme]

"Computers shouldn't be more like brains..

cuzz what if the get a mind of there own...

who knows what could happen lol just like the movie I-robot with will smith :P"

That can't happen, trust me,

the hardwirers and programmers will

always be in control of what it can

and can't do, unlike in unrealistic movies

that have no scientific basis or logics whatsoever.

[headshotjoe]

Making of the network like processor requires alot of work and designing. It would be the easiest task to implent a bottleneck into the network like processor to put resrictions to the

processor that it cannot dybass.

[donpapaspliff]

Very interesting, this guy is smart but I dont get the joke about not enough africa in computers.some one explain.

[theyellowdart12]

africas pretty crazy , think he means computers are too rigid

[MNIKELL]

the joke is that Africans keep on trying other ways till it click. in reference to African mechanic or technicians.

these are the kind of videos we need to watch not those movies with stupid stuff.

thank you i wish i could write to you.

thanks

[bajan13k]

In a previous TED talk, they explained that the binary number system, trans-finite mathematics/fractal generation, and so on are built into African rural life, and in fact that the binary number system migrated from Africa, being adapted as the Boolean number system later on. Or something like htat.

[tesla4d]

Oooh, which talk?

[bajan13k]

Ron Eglash: African fractals, in buildings and braids

[tesla4d]

THANK YOU

[ednavelho]

cool

[CheezMonsterCrazy]

Liked the vid... but his laugh is teeny bit on the annoying side. :P I've heard worse though.

[VolumePerfection]

he is a ghanian (:

[yoyoko520]

居然动都不动一下

[andreawww]

YAAAA

[recoordant]

Interesting talk.

[SchumannSC]

the reason we learn is because of inputs already in our brain, such as happiness is something we go to, pain is something we go from, using that data we learn consciousness, how would we teach a computer this? it would have to be evolved .

[BaganJermal]

About the Brian Eno quote, "The computers need more Africa in them.". Does it refer to the scarce resources (eg: energy) that the computer must use to be as efficient as brain? Or does he means something else?

[SchumannSC]

maybe in africa there are no central processors... I.E. presidents etc?

[TheBlasphemer2875]

Yeah I think Schumann is right.

[cmielack]

i think it means that we need more people with new and different ideas, perspectives and approaches to problems.

As he said, the computer was a new and special thing to him and he didn't just accept it, but questioned it, whereas in western culture it was more or less accepted as it was.

So growing up in a different environment can make a big difference, thats how i understand it, but as a sidenode i don't think he was the first human to say that computers should work more like brains...

[b4skin]

Kwabena comes off racist/seperatist to me. To presuppose AFRICAN-infused conceptuality would be a radical difference instead of drawing cultural similarities THROUGH the differences such as the piano/drum display is disappointing (which is to say that the access to the information of defining tonal qualities within an object isn't 'owned' by a race/culture, though the tool/object may be).

[camipco]

He's talking before a mostly white audience in Canada. He's probably not too radical a separatist :)

Also, he only mentions Africa twice in the 15 minutes of the talk, it's clearly not the focus of his work.

[b4skin]

Him saying,"I'm not the 1st 1 to figure this out,"The problem with computers is that there is not enough Africa in them" leads me to question his perspective in proposing that. whereas i'm supportive in cultural differences tackling issues through competing perspectives, I did not hear him propose them, instead he made what sounded to me a racial blanket comment on how computers would be 'better' if "more Africa" was in them. My use of "racist/seperatist" was certainly wrong to call HIM.

[bizarreworld123]

Is Arusha, Tanzania located in Canada?

[method4uandme]

no its in africa

[ghanboy]

ha ha, cute.

[Hujiki1]

this guy is well cool... i wud love to employ him...

[SchumannSC]

smarten up maybe you can work for him

[celshader]

I like his point that people from Africa Will approach scientific and technology problems with a different perspective because they have not grown up with western popular culture and science fiction.

[truefictions]

Why does it take over a year for TED videos to show up on You Tube? Isn't that a bit pathetic?

The guy sais it is 2007, last time I checked we are in 2008.

[gwailogavin]

They didn't used to make these videos public at all, so even a year late we're lucky to see them.

[buckfushes]

If you know that you exist, you are self conscious. Plus, it will be easy to give a computer many many years of "experience" with programing.

[sacapiloa]

wonderful

[EvanChaim]

I like his laugh!

[ogjimkenobi]

Hell yeah, what an awesome video. I saw it up on the TED site and just hadn't looked into it yet.
