Now that costs and barriers to creating what might at first glance pass as a "game" is nearing zero there's a lot of money to be made if you can trick a enough gamers into buying your low-priced trash titles because you can bet that some percentage of those players won't bother requesting a refund and may not even play the game. I myself have a huge amount of cheap games I've paid for, but haven't gotten around to.
Even developers that won't just be spamming out as many garbage-tier games as possible will probably be using AI extensively. Maybe one day, in the distant future, AI will be good enough that it won't matter and AI could even become a good thing, but in the meantime we should expect steam to become a minefield where every other game on the platform is filled with terrible AI generated graphics, terrible AI writing, and "live" AI features shoehorned in because it's easier than creating actual content and allows for new kinds of data collection.
