If you can point me to somewhere that you can just buy 808/909 sounds to distribute in a DAW please let me know, but everything I've seen is basciallyjust limited to making music. As far as I know Ableton, etc. have (or work with) actual sound designers which either create samples from the actual hardware or they re-create them digitally. Which is what LLM's try to do but fail at.

To be clear, I think sounds synthesized by LLMs and public domain stuff goes a very long way. But when you want to create something very specific you're going to run into a wall. Same for 3d models, video, etc.
