We're already there when it comes to music. We have a lot of virtuoso musicianship today. You want top-tier jazz? You can find it. Bossa Nova? Yep. Orchestral arrangements? Those too. Blues and old-school rock? Still being made. But we no longer have music as a common cultural touchstone: everything's been atomized to hell, fragmented into perfectly-curated Spotify ML-recommended playlists. People no longer use music to connect to each other. It's more about individual hedonic enjoyment.
As goes music, so goes all entertainment and all media. When everything is perfectly tailored to each individual's preferences, what we're left with isn't so much culture (which in its essence is about commonality) as much as aesthetic pornography.
