Yeah, I assumed the general consensus was "alt coins" in crypto or the scams themselves are the "bubble". But, Ethereum and initial projects that basically create the foundational technologies (smart contracts, etc) are still respected and I'd say has a use case, but is not "production ready?". So for AI/ML in LLMs at least, things like LLaMa, Stability's, GPT's, Anthropic's Claude, are not included in this bubble, since they aren't necessarily built on top of each other, but are separate implementations of a foundation. But, anything a layer higher maybe is.
