Waymo showed that under tightly controlled conditions humans can successfully operate cars remotely. Which is still really useful, but a far cry from the promise of everyone being able to buy a personal pod on wheels that takes you to and fro, no matter where you want to go, while you sleep that the bubble was premised on. In other words, Waymo has proven the bubble. It has been 20 years since Stanley, and I still have never seen a self-driving car in person. And I reside in an area that was officially designated by the government for self-driving car testing!
> I think the realistic answer is we don't actually know if it's a bubble.
While that is technically true, has there ever not been a bubble when people start dreaming about what could be? Even if AI heads towards being everything we hope it can become, it still seems highly likely that people have dreamed up uses for the potential of AI that aren't actually useful. The PetsGPT.com-types can still create a bubble even if the underlying technology is all that and more.
