But the opposite has happened on the other end of the spectrum. Emancipator or Bonobo (or Romare or Pilotpriest or or Nicola Cruz or Nu or Pantha du Prince or Sampha) are just leagues better than what we had even ten years ago. Sure the mass market is drinking down Fast and the Furious 9 or Transformers 11 or Spiderman ∞, but the quality of the films that are targeted at the intelligentsia is head and shoulders above what we used to have. Even television has stratified.
I think the internet has something to do with it. People follow people that are smarter than them because they learn from them or they interact with smarter people more because they tend to get upvoted more, but there is a window of potential interaction. None of my family members are on HN and very few of them follow me on Twitter (out of the 130+ of them). Then you move the smart people to the smart cities and the normal, day-to-day interaction that would have happened no longer does.
