I think you have this the wrong way around. The article is undoubtedly correct to my mind. The most popular content creators are basically doing nothing. Looking at the truly huge Youtubers, people on Patreon, Instagrammers, streamers etc it is clear that mundanity with high production values is what people want. This is non-art served up with the orchestra and vino that you are criticising as bourgeois. Reality TV gets it wrong with exotic locales, tattooed narcissists and manufactured drama, that's too much actually. People seemingly just want a nicer, sanitised version of their own lives served up to them. They will swallow this all day every day.

The saving grace I think are podcasts. There is some authentic intellectual stuff going on there, it's a renaissance medium that humanises debate and invites nuance and complexity.
