I'm inclined to believe that filling the service with an endless stream of generated garbage is their ultimate endgame - why bother with unreliable and costly human creators when you can just emulate them well enough for undiscerning listeners. No substance, just vibes.
No, that's the end game here. People already mostly have parasocial relationships with artists. There's already famous AI personality Instagrams and Vtubers. With the advent of Generative AI video like Sora and Generative AI music like Suno, people will find their perfect generative AI niche and follow an artist story/interaction that they can't even tell is real or not. Generative AI will create millions of niches, it will hit that spot.
I find it really hard to imagine people following famous AI personalities as much as real musicians if they know that the AI are AI. Humans are social creatures.
I guess at some point there will be a popular "musician" who is relieved to be an algorithm, and we'll see what happens.
We're already seeing an explosion of people doing AI chatbot therapy and AI relationships. "Human-ness" factoring into someone's enjoyment of music is already below well below both of those.
