This "running out of data" thing suggests that there is something fundamentally wrong with how things are working. A new driver does not need to experience 8000 different rabbit-on-road situations from all angles to know to slow down when we see one on the road. Similarly we don't need 10,000 addition examples to learn how to add. It is as though there is no generalization in the models - just fundamentally search.

i think you underestimate the amount of data a driver experiences in a single 5 minute drive

I never get this argument.

I've seen a deer on a road maybe once. I've seen a rabbit on a road zero times. But I know what to do if I see one.

Is that because the "video" of my perception has many "frames"? Even if that's true at some level, I think it's massively missing the point. Yeah, so I saw that one deer from a lot of angles. But current AI training is like the equivalent of taking every deer that has ever been on camera in the history of the human species.

Somehow I'm still dramatically better at generalization than the AI. Surely that's an algorithm difference.

You might personally have seen a deer just once, but human evolution, and animal evolution prior to that have practiced this skill a lot. AI doesn't have the advantage of evolutionary priors baked in, so it needs explicit walking through many combinations to infer its structure from data, and is remarkably efficient. GPT-4 'only' trained on the amount of language that 30,000 humans use in their lifetime.

But we have seen from AlphaGo that when training data is extensive, it can rediscover strategy on its own and even surpass us. It's not inherently worse than human learning.

Which pre-human animals evolved instincts for swerving a car to avoid a deer?

I'm pretty sure that evolution would select out anything that could not generalize pretty quickly.
