Hollywood execs have been salivating at the idea of just generating media with AI, there was a whole strike about it. Same with video games, I believe game voice actors got screwed with that AI deal.
Also NFTs had some tech that could have been useful but instead people chose to use it for creating a new speculative market riddled with scams. That's my comparison to AI, interesting tech used for a very wrong purpose.
The copyrighted material has no business being used for AI training anyways. Like why train AI to write books or make art when you could feed it documentation and teach it data entry instead like stuff that would actually work well for this and wouldn't require copyrighted works.
