Maybe it's a computer verified proof, but still it says that under no circumstances is this car just going to swerve into oncoming traffic.

And I think even in very short term, if you look at how, you know, today, right, this absolutely pathetic state of cybersecurity that we have, where is it, 3 billion Yahoo accounts were hacked, almost every American's credit card and so on.

You know, why is this happening?

It's ultimately happening because we have software that nobody fully understood how it worked.

That's why the bugs hadn't been found, right?

And I think AI can be used very effectively for offense, for hacking, but it can also be used for defense, hopefully automating verifiability and creating systems that are built in different ways so you can actually prove things about them.

Right.

And it's important.

Great.

I think there are a number of very important insights, very important lessons we can all redraw from these kind of successes.

One of them is when you look at the human brain, you see it's very complicated.

10th of 11 neurons, and there are all these different kinds of neurons, and yada yada, and there's been this long debate about whether the fact that we have dozens of different kinds is actually necessary for intelligence.

We can now, I think, quite convincingly answer that question of no.

It's enough to have just one kind.

If you look under the hood of alpha zero, there's only one kind of neuron, and it's ridiculously simple.

Simple mathematical thing.

It's just like in physics.

If you have a gas with waves in it, it's not the detailed nature of the molecule that matters.

It's the collective behavior somehow.

Similarly, it's this higher level structure of the network that matters, not that you have 20 kinds of neurons.
