That's not to say that celebrity isn't a form of inequality or some perfect meritocracy, but your face and voice being used by others isn't inherently democratizing, but instead advantages bad actors.
It won't be too long before enough talented nobodies sell everything about themselves for personally life changing amounts, that we can create anything from scratch on the fly.
But there will always be other types of celebrities.
I imagine that it won’t be too long until you don’t need a real human anymore, and we can generate realistic human characters at will.
At that point, why would we still plug real humans into the replication machine? It will be considered old fashioned very quickly.
