That said, I feel like the comparison isn't exactly perfect here. Both AI and crypto do have some valid use cases, even if the majority of interest is completely pointless and makes no sense. While something like NFTs are beyond worthless, the tech behind a blockchain or LLM is something that can be used for a bunch of other purposes.
So, I don't think it's accurate to compare them to Enron. Enron was a scam first and foremost, and delivered nothing. Both crypto and AI are potentially useful technologies pumped up to an absurd degree by a broken market, sorta similar to the dotcom boom in the 90s.
This assertion is becoming harder and harder to take seriously as time goes on. Bitcoin was released in 2009; it's been seventeen years. Pushing it to zero would require a massive, global, coordinated, effective campaign to completely eliminate its use. It's not clear that this is even possible, let alone incentive compatible for governments.
