and honestly most "mainstream" nerd stuff has been around for decades. And all of the "accepted" things are pretty safe overall. Gaming is "accepted" now because of COD and the like (and phone games of course). Marvel is what's hot right now. Star Trek saw its recent boom with the blockbuster styled movies. And most of it is a very set formula.
Snarky protags, epic action, passable plots that don't require too much backstory.
This isn't a bad thing by no means (I have enjoyed all of the Marvel films of late because they do the one thing I want them to do; have superheros do cool shit) but it is what it is.
This is why some of the more obscure properties spend a long time as vaporware or never comes out.
This is also why actually reading comics is still niche. Certain genres of gaming are still niche or dying. And this is why anime/manga have such an uphill battle to be "accepted". A lot of stuff has to change and a lot of those changes would alienate the die hards and potentially end up not pleasing anyone. Kinda like the early Marvel films lol.
I don't think geek culture is assimilating..just that the long running properties have begun to be able to be adapted to appeal to the masses without pissing a lot of people off. And while those properties are big. They aren't the end all be all of geek culture. Not even close
Ehhhh, I don't know about that. Maybe if we're talking about the truly iconic stuff like Superman or Batman, but from what I've been told by people who lived through it in the 80s there was genuine social ostracization around "weird" stuff. Being that kid at school who liked horror movies or played D&D had real consequences. I think this really started to change in the 90s and by the time I was in high-school in the mid 2000s really no-one gave a fuck anymore about what you liked (hell our homecoming king was an avid Magic player). I usually say that I don't think the word "geek" means anything anymore because that social dynamic just doesn't exist, either everyone is a geek or no-one is, but you know, anime might be the last place where that still exists at that level. People may not be reading comics en masse, but the reaction to you telling people you're reading a comic book will be very different than it was in say, 1990
