Well, just as financial capitalism has replaced classical producer capitalism, so now the "digital" capitalism of social networks is replacing financial capitalism. Influence becomes a value. People are starting to sell themselves as a commodity with influence. But only a media personality created in the space of a social network is not a real person. I immediately think of something similar to Jean Baudrillard's simulacrum.

By the way, there is already a theory of post-capitalism on this topic, built around the concepts of personalitet/impersonalitet.
There, influential individuals act as the "new aristocracy," while everyone else is an impersonal crowd. At the same time, the reputational position of the simulacra is too precarious (any event can reset the "capital of influence"), as evidenced by the Kanye West example you gave.
