The sort of AI generation we're seeing now seems like revolutionary tech that came out of nowhere, but it really isn't. The underlying tech has been under development for decades and has just now reached the status of "oh, we can turn this into something that might pass muster if you don't look at it too hard". Fundamentally replacing human creatives, or even the workaday illustrator toiling in the Simpsons mines, won't happen until humanity creates an AI that can actually think. And it wouldn't surprise me if we got Ragnarok or the Second Coming of Christ before that happens.
Iteration and ease of use upgrades on the current stuff won't replace humans, but it should be more then enough to replace *most* human creatives in certain fields.
So instead of needing 10 animators you need 5, instead of hiring a logo design specialist you do it in house with Stable Diffusion type tools, or instead of hiring someone on commission for your quest for like 50(?) bucks per image you do it yourself or hire someone to do it for 5 bucks per image instead.
This doesn't just apply to artist either, entire fields (accountants, programmers, customer support/tech support via phone) and ripe to having the number of people needed cut down significantly for the same quality of work.
None of that stuff requires fundamental technology advances, and in some cases is currently happening.
Yes, going from 10 animators to 0 requires some pretty fundamental advances, but its really really going to suck for artists long before then.

I still disagree with the notion that AI isn't going to continue to advance at a really rapid pace though, and we don't need true strong AI to fundamentally revolutionize the entire world.
