I've noticed the same thing with other fields as well, not just art. Cooking is this way, for example. The food that fancy chefs at fancy restaurants make is so ridiculous that it feels like a joke sometimes. And as far as I can tell, it's the same thing. Those chefs are bored of normal food, are trying super hard to make something creative that has never been done before, and have lost sight of the fact that it's just not going to appeal to people who aren't as bored with food as they are. Maybe it's the inevitable result of being steeped in a craft and spending all your time on it, IDK.
Even when I make art with other people in mind I still give preference to my own personal aesthetic impulses. Art isn't always a product seeking product market fit.
