loved the analogies! Karpathy is consistently one of the clearest thinkers out there.

interesting that Waymo could do uninterrupted trips back in 2013, wonder what took them so long to expand? regulation? tailend of driving optimization issues?

noticed one of the slides had a cross over 'AGI 2027'... ai-2027.com :)

Eh, he ran Teslas self driving division and put them into a direction that is never going to fully work.

What they should have done is a) trained a neural net to represent sequence of frames into a physical environment, and b)leveraged Mu Zero, so that self driving system basically builds out parallel simulations into the future, and does a search on the best course of action to take.

Because thats pretty much what makes humans great drivers. We don't need to know what a cone is - we internally compute that something that is an object on the road that we are driving towards is going to result in a negative outcome when we collide with it.

I don't think that would have worked either.

But if they'd gone for radars and lidars and a bunch of sensors and then enough processing hardware to actually fuse that, then I think they could have built something that had a chance of working.

Think about this. If I give you GTA 5 traffic in single player with only NPC drivers, could you manually write a policy that gets a player from point a to point b in a car, assuming you have in game positions of all cars?
