A dirty secret is the algorithms can't differentiate real users from fake.
The universe of content is so large now, if you don't start with a fake audience you go nowhere. Slop rises to the top, because slopfarms can spend all their money on the farming rather than the content. It's even worse if you look at short form video because it's trivial to clone anything that went viral and alter the message, no real human or attractive 20 year old American required.
If content requires a real human network for transmission, the cost of transmitting slop is your own reputation within your network. A bunch of bots circle jerking each other can't sell concert tickets or much of anything.
The idea that some artist is exceptionally talented and good and they deserve to be famous or sell out concerts is a myth. There are so many exceptionally skilled singers, songwriters, and musicians that are all unknowns. Many who are more talented than (insert famous living or dead pop star here.)
I think this is part of the reason why the AI ruins creativity is overblown. The music-art-talent pyramid always meant a tiny percent at the top walked away with all of the money. Look at the numbers from the last screen actor's guild strike, the majority of actors earn at or below minimum wage. It's a new world, and the old one people believe deserves to continue perpetually existed in but a blink of human civilization.
