PGM has a massive ethically produced library. Their main problem is making it difficult for beginners (and more advanced users) to work with it, discover deep hidden features aka workflow + known issues. Several recent PGM threads collecting opinions makes me hopeful that something significant is cooking. They obviously need to re-tool.

I guess, to me personally it is more about ethics and just having fun in manual tinkering. AI can definitely play a part in future of PGM. For example enhance RTs: more interesting transitions, different octaves, allow for significant tempo changes without artifacts, etc. I still prefer this "semi-manual" algorithmic philosophy of BIAB composing / constructing vs "one click" AI generation.
