Is A.I. Actually a Bubble?

I suspect what comprises the majority of the ai bubble is closer to the subprime mortgage / housing bubble than the dotcom one. More of the money and fallout is tied to real estate and debt deals being all topsy turvy.

There are a bunch of companies that amount to a good prompt + tools, and there is certainly an amount of dotcom feeling there, but the money side of those seems tiny by comparison to the infra investments at the top of the tech food chain
