I think back when it was just actors, musicians, athletes, etc. it was in a time when there were gatekeepers for whether or not those people had any actual talent in an art.
Whether or not those gatekeepers were right is another matter, but there was some guy in an office in a skyscraper who you had to impress, and if you did, you could get in.
Now, that guy's effectively gone. Aiden Ross, Jack Doherty - that kind of guy - couldn't have impressed a big wig. But now, they don't have to. They have to make people pay attention to them on YouTube/Instagram/TikTok/Twitch, and that's it. And they do that and they can get people to give them insane money to do so because they want access to that audience. Quality doesn't matter anymore.
