Geek culture has always been commodity fetishism. Your favorite TV show, movie, video game, comic book, sff novel, operating system, programming language, RPG, text editor, or even heavy metal album is not a substitute for having an actual personality.
(This is as much a reminder for myself as an admonishment to everybody else.)
This goes without saying and you should focus on internal aspects of yourself first.
In my experience geek culture has always been a way to get away from rampant consumerism and the lack of creativity of the mainstream. Now it feels like it's been turned into a mindless money maker instead of a meaningful hobby. With anime going mainstream, companies now know what sells and they are gonna pump out nothing but that. Marvel has been milked so hard it's crazy. It just used to be a safe space and now it doesn't always feel like that anymore. Though I do agree that making a part of yourself the only thing there is dumb.
