I think genAI has been strictly worse for humanity. It's destroying the quality of our industry, it turns creative fields into slop, etc. It is all downside and no benefit, in my opinion.
The last season of Poker Face was really bad, especially the last few episodes. Come to find out Natasha Lyonne is big into AI and I have no doubt they had their AI slop out the plot and writing for the last few episodes. The writing went off a cliff, it was really, really bad compared to the first season. The show ended with me thinking WTF did I just waste my time watching? I have no doubt it was AI slop.
I guarantee you, good-quality AI generated art you see every day without noticing it.
