I mean...I won't be surprised if you turn out to be right. However, I will be frustrated and disappointed because AI just ain't there yet (and may never be)! It's mostly smoke and mirrors at this point, but so many people have been hoodwinked by the tech bros.
1) Large Language Models will never get there, and really that's all we're looking at. But they -are- good at generating piles of to-format content which is what most D&D writing is. "Make a CR 15 Monster based on the monster art you just created from my prompts." and BAM. Instant new monster 'cause the template is easy enough to fill out.
2) It'll solve Hasbro's biggest problem when it comes to money leaving the pockets of executives: Wages.
'Cause that's the ultimate bottom-line issue for them. If they can avoid paying wages they can keep that money, too.
