That’s wrong on both counts.

The complaints about NFTs were also that they were unethical - consumed a shitton of electricity for no reason, sustained themselves mostly by scams and rugpulls. The chief use case of crypto has always been crime and money laundering.

The complaints about AI are that it fucking sucks and results in a truly insane waste of resources towards something that doesn’t solve literally any problems, like NFTs squared. The unethical aspect of it all is just a cherry on top that makes using LLMs a no-go even if it happened to kinda work for your problem.
