Geoffrey Hinton says a big language model runs on about 1% of your brain's connections and still ends up knowing more than you: "So in your brain, you have a hundred trillion connections, roughly speaking. Okay. That's a lot. And you only live for about two billion seconds. That's not much." "If you compare how many seconds you live for, with how many connections you've got, you have a whole lot more connections than experiences." "Now with these neural nets, it's sort of the other way round. They only have of the order of a trillion connections. So like 1% of your connections, even in a big language model, many of them fewer, but they get thousands of times more experience than you." "So the big language models are solving the problem with not many connections, only a trillion. How do I make use of a huge amount of experience?" "And back propagation is really, really good at packing huge amounts of knowledge into not many connections." "But that's not the problem we're solving. We've got huge numbers of connections, not much experience. We need to sort of extract the most we can from each experience." Two to three billion seconds is the whole budget. Everything you know, you learned inside it. So evolution built you to squeeze a lot out of very little. Hinton's point is that a language model has the opposite problem and the opposite fix, and backprop turned out to be extremely good at that fix. Worth noticing what this predicts about failure. A system running on 1% of your wiring and thousands of times your experience is not going to fail the way you do. You fail from having seen too few examples. It fails from compressing too many into too little, and the compression is where the errors get made. That is a strange thing to be deploying into hospitals and courts with no way to inspect it. We test these systems by asking them questions, which tells you what came out. Nobody can yet look at a trillion connections and say what got packed in. - Geoffrey Hinton, Nobel laureate and Turing Award winner, on StarTalk (@StarTalkRadio) with Neil deGrasse Tyson.

Mike Tyson says he quit cocaine and alcohol for 5 years after smoking toad venom “I had the experience of smoking some of the toad venom that comes from the toad. You bust its little pimple and the puss comes out. We put it on a window or a mirror, it hardens up, we make fine ash out of it, like sawdust or whatever, and we smoke it” “Then we smoke it, and once you smoke it, let the smoke out. You hold it for as long as possible. You let it out, and then you go to another dimension. Then you realize all you did in life, you didn't do shit. This is the closest I ever been to God” “Oh shit, it'll blow your motherfucking mind. It will blow your mind for you to know how powerful you are. I did it around 60 times. It's always a different experience. It blows your mind what you saw” “I saw the ancient shit, like the Aztec, shit from Africa. I saw my ancestors during prehistoric times. It's really creepy. And then next thing you know, you wake up and you're crying or something” “If I ever saw somebody take it before I did, I would never take it. I was high. I was on cocaine. I was on cocaine when I took it. I was doing crazy shit. I took that, I ain't get high for five years. Didn't touch liquor or cocaine in five years. I was 100 pounds overweight. I got in shape to fight. That's what that did to me”
