Yeah. I mean you're right and wrong at the same time imo. I won't hypothesize about how humans drive. I think for the most part it's a futile exercise and I'll leave that to the people who have better understanding of neuroscience. (I hate when ML/CS people pretend to be experts at everything).

That being said, this idea of a latent space representation of the world is the right tree to be barking up (imo). The problem with "scale it like an LLM" right now is that 3D scene understanding (currently) requires labels. And LLMs scale the way they do because they don't require labels. They structure the problem as next token prediction and can scale up unsupervised (their state space/vocabulary is also much smaller). And without going into too much detail, myself (and others I know in this field) are actively doing research to resolve these issues so perhaps we really will get there someday.

Until then however. Sensors are king, and anyone selling you "self-driving" without them is lying to you :)

Correction: anyone selling you "self driving" is lying to you.

We're at least a decade away from it... (and yes, I've seen the current batch of FSD videos).

I think you may be over-indexing on the word "selling". I didn't mean it literally as in for sale to you (the customer) directly. That is what Tesla FSD is claiming and I agree with you that we're some indeterminate amount of time away from it.

However Waymo, Cruise and others do exist. If you haven't already, check out JJRicks videos on YouTube. I think you might be changing the number of years in your estimation ;)
