> 1... The narrative/life of the artist becomes a lot more important.
When I watch a movie, I don't care about the artist's life. I care about character life, that's very different.
> 2... Originality matters more than ever. By design, these tools can only copy and mix things that already exist.
It's like you assigning to humans divine capabilities :) . Hyperbolizing a little, humans also only copy and mix - where do you think originality comes from? Granted, AI isn't at the level of humans yet, but they improve here.
> 4... It's not going to get better, because the lack of taste isn't a technical problem.
Engineers are in business of converting non-technical problems into technical ones. Just like AI now is way more capable than it was 20 years ago, and able to write interesting texts and make interesting pictures - something which at the time wasn't considered a technical problem - with time what we perceive as "taste" may likely improve.
> 5... Above all, AI art is uncool, which means it has no real future as a leading art form.
AI critics are for a long time mistaking the level with trend. Or, giving a comparison with SpaceX achievements, "you're currently here" - when there was a list of "first, get to the orbit, then we'll talk", "first, start regular payload deliveries to orbit, then we'll talk", "first, land the stage... send crewed capsule... do that in numbers..." and then, currently "first, send the Starship to orbit". "You're currently here" is the always existing point which isn't achieved at the moment and which gives to critics something to point to and mount the objection to the process as a whole, because, see, this particular thing isn't achieved yet.
You assume AI won't be able to make cool art with time. AI critics were shown time and time again to be underestimating the possibilities. Some people find it hard to learn in some particular topics.
