Stuart Russell

You're constantly coming up with situations you haven't seen before.

And you have to reason about them.

And you have to think about, okay, here are the possible things I could do.

Here are the outcomes.

Here's how desirable the outcomes are.

And then pick the right one.

You know, in the 90s, we were saying, okay, this is how you're going to have to do automated vehicles.

They're going to have to have look ahead capability.

But the look ahead for driving is more difficult than it is for chess.

Because of humans.

Right.

There's humans and they're less predictable.

Than chess pieces.

Well, then you have an opponent in chess who's also somewhat unpredictable.

But, for example, in chess, you always know the opponent's intention.

They're trying to beat you, right?

Whereas in driving, you don't know, is this guy trying to turn left, or has he just forgotten to turn off his turn signal, or is he drunk, or is he changing the channel on his radio, or whatever it might be.

You've got to try and figure out the mental state, the intent of the other drivers to forecast the possible evolutions of their trajectories

And then you've got to figure out, okay, which is the trajectory for me that's going to be safest.

And those all interact with each other because the other driver is going to react to your trajectory and so on.
