I wouldn’t have any confidence in any predictions I make 100 years into the future even if we didn’t have the current AI developments.

With that said, I’m pretty confident that the movie industry will exist in 10 years (maybe heavily tranformed, but still existing and still pretty big). If it’s still a big part of current popculture by then (vs obviously on its way out) then I’d expect a collapse of it to require a change that is not a result of AI proliferation, but something else entirely.
