However, I think modern rec algorithms (like the Netflix home page) are recommending more mediocre stuff than the old system, and the streaming boom did produce an abnormal glut of junk.
Anyway I think AI is going to spawn a music remixing/game modding/tv extending renaissance. They perform much better when pointing them at a good source (as you can see with the melody conditioning samples, and other stuff like sd img2img and finetuned llms).
