A better example would be Spotify replacing artist-made music recommandations with low-quality alternatives, to reduce what it pays to artists. Everyone except Spotify loses in this scenario.
The future with AI is not going to be our current world with some parts replaced by AI. It will be a whole new way of life.
Water cooler talk about what happened this week in M.A.S.H. or Friends is extinct.
Worse, in the long run even community may be synthesized. If a friend is meat or if they're silicon (or even carbon fiber!), does it matter if you can't tell the difference? It might to pre-modern boomers like me and you.
Virtual influencers might be a big thing, Hatsune Miku has lots of fans. But it's still a shared fandom.
