> How can you both think AI will do a soulless garbage job and that it will displace all the creative people who put their blood sweat and tears into doing art.

They don't, that's why they're saying 20% of creative departments will remain. The part that will go is the part that's already soulless - making ads in the style of the current trendy drama series or what have you.

> If you think it can be 20 times easier to make a movie, then it seems to me that it would be 20 times less impactful to make a creative work, since the market should quickly react to creative success by making a ton of cheap knockoffs of your work until the dead horse is so thoroughly beaten that it's no longer even worth paying an AI to spit out cheap knock-offs

That seems pretty backwards, given Jevons paradox. The ease of writing knock-off fanfiction didn't mean people stopped writing novels. The average novel probably has a lot less impact now than in the past, but the big hits are bigger than ever.

You may not understand that creativity and work are literally one and the same thing.
