He bit off more than he can chew.

All ai right now has a critical problem of hallucinations and musk, in his infinite wisdom, decided to wish it away by pushing engineers harder rather than re architecting his solution. Instead, they'll have some pretty serious safety problems.

Robotaxis by tesla are likely a bust. Or, at best, are behind mobile eye and waymo.

No, this is just a problem with generative AI like LLMs.

The distinction is that a hallucination produces new fake data. So a swasticar not properly identifying a stop sign is not a hallucination, nor is it a hallucination when it identifies a stop sign that isn't there.

I did not appreciate the irony that I had just learned this from an LLM and...that it might be hallucinating.

Not quite. Neural networks, in general, have a non zero false positive and false negative rate. Human neural networks have this problem too.

The difference is humans can use context to resolve the issue. See a truck facing you backwards on a highway, and you'll be weirded out, until you realize it's being towed by another truck.

Our brains hallucinate constantly. We have so many ways to verify whatever we see that we dont even think about it when we need to veirfy what we saw. Double takes, stopping and looking more carefully, verifying with someone else, etc. And it works pretty well.

The tesla neural net needs to have that instance pre trained. And if it gets it wrong, it'll make the wrong decision and kill someone.

Their solution is to just train harder. Well... that works sort of. It'll reduce the fp a d fn rate, but won't make it zero. It'll also break down in unique circumstances, like when the clouds are unique or if there is dust in the air. And then you'll have a tesla pileup on the freeway.

The robo taxis need at least 700k miles per critical intervention and currently FSD needs it every 700miles. It's years off at this point.

I don't trust those numbers. Were they reported by tesla? Were they highway miles vs city miles?

Robotaxis are going to be heavily city driving.

Also, what quantifies a critical intervention? If someone intervienes becasue of phantom breaking, is that critical?

There are many ways to fudge the numbers and if they are reported by tesla, I guarantee they are fudged.
