Transcripts

Time to talk about AI. Right now, we're  in this weird moment where lots of smart  

people agree that we're on the cusp of  this truly world-changing technology

but some of them seem to be saying it's  going to kill us all, while others are  

saying it's more profound than fire...

"You know, I've always thought of AI as the most profound technology,

more profound than fire or electricity..."

It's clear at this point that something big is happening. But my problem is, it's all just so

vague. I want to know: How specifically  would AI kill me? Or how would it dramatically  

transform my life for the better? In this video, that's what I'm going to try to figure out, what

the most extreme bad and good possible features  with AI actually look like, so that you and I can  

get ready. And more importantly, so that we can  be a part of making sure that our real future

goes right.

"Artificial intelligence -" "artificial  intelligence -"

"artificial intelligence"

"the benefits vastly outweigh the risks"

"eventually they will completely out-think their makers -"

"AI to begin to kill humans -"

"AI has the potential to change society"

"and a lot of people can be replaced by this technology"

"Is this depressing? I don't see why it should be..."

"This will be the greatest technology humanity has yet developed."

To understand why you're seeing so many mind-blowing AI tools

all of a sudden, you need to understand how they  actually work. And to do that we need to play some  

chess. This isn't one of those "oh my god, AI beats  a person" kind of games. In this game, neither of the  

players are human. One is a famous chess engine, a  system programmed by humans with insanely complex  

rules for how to play the game. The other is using  a very different strategy. And that second player  

absolutely crushed the first...

"It had learned the game without any of those rules, it just

watched enough games to see what winning looked like."

That is Eric Schmidt, former CEO of Google  

and chairman of its parent company, Alphabet.

Yeah.

He was chairman of the company when they created that second player, AlphaZero.

"Before that moment all of the game playing was done algorithmically,

move here, evaluate this, do the math that..."

But that's not how AlphaZero worked...

"It didn't understand the principles of what a rook and a  pawn and so forth and so on, it just knew how to  

play because it had observed enough games and it learned how to win."

In other words, our best systems had gone from using

human-given rules to win, to using observation to win.

"So you can think of that as moving from algorithms to learning. That to me was a major major deal."

That ability to learn changed everything. It's what makes incredible tools like ChatGPT possible today.

You now know this technique as

"machine learning"

"Machine Learning!"

"machine learning..."

The reason that it suddenly feels like "AI" is everywhere is because

of the incredible success of machine learning specifically. At a basic level,

the idea is that instead of giving a computer a rigid set of rules

that says "if this happens, then these are the  possible outcomes," instead you give a computer a  

set of inputs and outputs and allow it to create  the rules that turn one into the other. Meaning  

that it might come up with rules that we didn't  think of or maybe don't even understand... but making  

the AI models that can do all the incredible  things that you see now just recently became  

possible. And it's because the computers training  them have gotten way more powerful. Look at this  

graph: So you see it going up and then around 2009  the computing power behind AI models just begins  

to explode. That change is largely thanks to a  switch in the physical technology used to do that  

training, going from CPUs to GPUs. My favorite  way to show the difference between CPUs and  

gpus is this Mythbusters demo back in 2009. That robot  right there represents a CPU and it shoots paint  

in these little sequential bursts. It can get the  job done but it's slow. And this robot represents  

a GPU so instead of shooting paint one little bit  at a time it can shoot in parallel. Basically, the  

physical tools behind AI are extremely powerful  now and they're getting even more powerful, fast.  

According to OpenAI, the amount of computing power  used in the largest AI models has been doubling  

every three months. This is why you're seeing  now AIs able to pass the bar exam, make more  

realistic images, answer more complex questions.  It's why this particular type of AI technology is  

"the risk that could lead to the extinction of humans"

"AI is a fundamental existential risk  for human civilization."

"How do we know we can keep control?"

So we have this technology that can learn. And it's learning fast. And so of course, in large

part thanks to Hollywood, we imagine that it'll learn to kill us.

"My CPU is a neural net processor, a learning computer"

but as much as these systems appear to be human, they're not. Why would they  

want to kill us? They don't want anything. And yet, Bill Gates, Sam Altman, and hundreds of other tech  

leaders recently signed a 22-word statement that  shocked me. I'll just read it to you: "Mitigating  

the risk of Extinction from AI should be a global  priority alongside other societal scale risks such  

as pandemics and nuclear war." That is an incredible  statement, that the development of AI is in the  

same realm of risk and importance as destruction  by nuclear war. To better understand why they feel  

this way I turn to this survey. This is the  same one that's been widely reported as "half  

of AI researchers give AI a 10% chance of causing  human extinction." The specific question that they  

were asked is, "what probability do you put on  human inability to control future advanced AI  

systems causing human extinction..." So what's going  on here? Well the surveyors summarized an argument  

for why AI might be so dangerous by saying "it's  essentially the old story of the genie in the lamp,  

or the sorcerer's apprentice, or King Midas: You get  exactly what you ask for not what you want."

Imagine this: In the future someone creates a powerful  machine learning system and gives it the desired  

output of a very accurate climate prediction. Then  the AI, using its self-created rules, figures out  

that the more computing hardware it can use the  more accurate its prediction will be. Then it  

figures out that by releasing a biological weapon  there would be fewer humans taking up the valuable  

computing hardware that it needs. So that's what it  does and then it gives its climate prediction to  

no one left. This is the category of thing that the  researchers mean when they say "a system optimizing  

a function of n variables will often set the  remaining unconstrained variables to extreme  

values." In other words, it might optimize for what  we tell it to do at the expense of other things  

that we care about. "You get exactly what you ask  for, not what you want." The term that researchers  

use for this is "specification gaming" and 82%  of the researchers surveyed agreed  

that it was an important or the most important  problem in AI today. Specification gaming leading  

to disaster becomes less likely if we work to  contain AI systems and we don't let them get  

connected to tools that might physically harm  humans. Like don't give them the nuclear codes

but how likely is anything like this to actually  happen? I honestly don't know and I think neither  

does anyone which is a big reason why all of  those tech CEOs signed that letter and why you  

might have heard people advocating for a pause  on AI development. However, there are real risks  

to not moving forward too. There's a fairly large  and impressive group of people now advocating  

for a pause on AI development. What do you think about that?

I think it's a terrible idea and the reason for that is

that a pause would give time for our  competitors which starts with China to catch up.  

At the moment the US is in a very strong position.  We have all of the top models, we have the majority  

of the researchers, we have the majority of the  hardware, we have the majority of the data that's  

being used. That's not going to be true forever,  but this is a critical time for us to build this  

technology in American values, liberal values, not authoritarian values."

So we've created these tools that have started to become so powerful

that we're concerned about how well they might do what we ask  

and at the same time every country, every company  is incentivized to build them first with their  

own interests in mind. But why should we want AI  in the first place? Like what's the goal here??

In my view, the most positive extreme case for AI  that I've heard isn't how much better or faster  

it can do the mundane things that we already do  it's how it could leap frog us to do things that  

we can't. You might be wondering, how? Because of  how incredibly good machine learning systems are  

at pattern matching, they can sometimes give us  results that we can verify are correct but we  

don't totally understand how it got there. It's  funny, it's the same skill that scares us is the  

one that gives this tool such incredible potential. And if you're feeling a little bit skeptical here  

that's totally fine and understandable, I was too,  until I heard this example: In 2021, researchers  

used machine learning on a problem that had up  until very recently been called "one of  

the most important yet unresolved issues of modern  science." It figured out the structure of a protein  

from just amino acid building blocks. For decades,  our best effort to do this has been to spend  

hundreds of thousands of dollars per protein to  shoot X-rays at them all in the hopes of learning  

just a little bit more about our own bodies and  make better medicines. This is how we got new  

treatments for diabetes and sickle cell disease,  breast cancer and the flu, but then researchers  

fed pairs of sequences and 3D structures that we  already knew into a machine learning system and  

allowed it to learn the patterns between them.  And the result was just incredible. We now have  

predicted 3D structures for nearly all proteins  known to science, more than 200 million of them.

"Deepmind's AlphaFold"

"AlphaFold"

"AlphFold was able to do in a matter of days what might take years!"

"solving an impossible problem in biology..."

I get a little emotional just thinking about this

about how many people's lives might actually get  better because of this knowledge explosion. And

this is just one example of what we've already  been able to do. As machine learning systems

get better and better, people have extremely high  hopes about what we might be able to use them for...

"We have lots of problems in the world. Think about  climate change, for example. Climate change will be  

solved to the degree it's solved by using techniques  that are very complicated and very powerful that  

will have as their basis generative AI. And I think that we want that future."

After learning more about AI and this moment that we're in

I think I've figured out why it feels so confusing and so hard:

We're living inside a trolley problem.

Down one path is the status quo, life without AI. But

with this incredible new tool we can pull  ourselves onto another path, one that could  

fundamentally change society. But we just don't  know, at what cost? Will AI give us what we ask  

for or what we actually want? In this video, we've  only talked about the most extreme futures with  

AI. In other episodes, we're going to go deep into  specific applications. We'll go full on Huge If True

into AI in music and news and robotics and  climate and food and sports and more to explore  

how these tools might transform our world. It's  easy to dismiss it as crazy when you hear someone  

say that AI might be "more profound than fire or  electricity" and while the cynical side of my brain  

wants to say that it's probably true that most of  the most ambitious AI efforts will likely fail, the  

more optimistic Huge If True side of my brain just keeps wondering:

What if they actually work?
