Eh, I mean you can pick and choose what you call an AI bubble, but the CV one in the early 2010s (remember when self-driving cars were going to be a thing any day now?) and the speech recognition one in the 90s, where MS was claiming that within years people would primarily interact with their computer by talking to it, were attainable with consumer hardware. They were just a bit shit.
Not that either were completely useless (and nor were, say, expert systems before them), but they ended up squarely in the “yeah, that’s an occasionally useful feature” space, rather than being transformative.
