I think the main attraction AI holds for so many people is NOT that it will produce highly-original content, but that it will produce professional-looking content, cheaply.
It merely needs to be passable, not original. They’re fine if it looks and sounds like everyone else. To them, that’s a win. That’s more than they had.
What they will end up with, is hack design and hack writing. Regurgitated tripe. Most won’t care.
The opportunity will be for those who can afford the real thing.
