The tech is good but not as good as advertised: note how Microsoft is simultaneously running ads saying Copilot can run your business and claiming it’s only for entertainment purposes in the EULA? Self-driving vehicles have a similar struggle where the manufacturers talk about the capabilities but aren’t willing to sign a legal agreement accepting liability for errors except in the easiest situations (and in the case of Waymo, only with pliable governments and control so they could immediately halt operations in the event of a major problem).

That’s more “build part of it, say you built all of it, and wonder why they don’t come”.

You’re generalizing too much here. One of the biggest problems with LLM’s today is in-fact that they are not at the level being advertised. This is not solely a case of regulation standing in the way of a «revolution».

This has not been my experience with Waymo. I drove a total of about ~3.5 hours in Waymos in LA when I was visiting and their robustness to very unusual situations absolutely floored me.

I am sure you can find truly out-of-distribution cases where the car will make a mistake, but the data shows that this is more rare than a human driver making a mistake.
