there's a whole world of wonderful radio that has been thriving for decades, completely different than Spotify or talk radio.
It's unfortunate that you haven't seemed to experience any of it, but I've personally loved over the years stations like KEXP, WPFW, Dublab, WUSC
KEXP is a local (and beloved) station for me. WIll have to give some of these others a listen if they're doing similar things.
Your original post said that we shouldn't be worried because people appreciate radio and music for reasons that presumably can't be replicated by AI. I'm asserting that's not true: it's not how most people listen to radio or music, and AI content is already quite prominent.
I'm perfectly familiar with KEXP and other stations like that, but this is not how most people experience the medium. It's like insisting that Taylor Swift will never catch on because her music is not nearly as rich and complex as Wagner. Sure, but that's completely irrelevant.
