Take https://www.patreon.com/sonicether who earns $50k a month creating shaders for Minecraft. That sounds mundane until you realise that he's probably enabling tens of thousands of people to create transcendent art from the comfort of their homes.
He doesn't think much of the artists creating comics either. Maybe he thinks only artists that display their work in galleries are "real" artists. Personally I think artists like Bill Watterson and Randall Munroe have done more to push the cultural zeitgeist than any artist in the last 30 years.
If you want to appreciate your fine classical works in a museum while listening to an orchestra and sipping your Pinot Noir, that's fine. But I think it's incorrect to presume to know what "real" culture is and labeling everything else "ordinary".
