The issue with current day "nerd culture" is that it's extremely self-referential. There's no space for anything outside of extremely codified artistic norms and genres. Techno-feudalistic art for a techno-feudalistic age.

We had artists like Sun Ra, Antonioni or Joffè who when asked about their artistic inspirations they would tell you it came from a photograph, from the sound of a specific tree in a park, the way a couple of unknowns they met everyday would talk to each other. If nowadays anyone, director or musician or artist, said anything like that he would be immediately labeled as a pretentious asshole.

All of that has been replaced in favor of an extremely rigid canon made out of permutations of themes found in marvel and dc comics, zombie books, Amblin-like '80s movies, anything strictly fantasy related from J. R. R. Tolkien (seriously, has anyone ever read anything not LoR related from this guy?) and a few other anime and scifi works.
