I don't think it's disliking tech people so much as disliking a monoculture.

True, but a city of "artists" is also a monoculture.

Less so, because in reality most "artists" actually end up doing normal jobs to make a living in a variety of fields and just keep art as a side interest. A city of hobbyist programmers wouldn't necessarily be a monoculture either.

In current realities that's probably true. I've read about a city (town) of artists in post WWI France, which was dominated by Americans who moved there to pursue their artistic interests (painting). They were regular American folks, but thanks to the wealth disparity between USA and France at the time, they were basically wealthy by French standards, which allowed them to live a life of leisure and do nothing but paint. In that city, there were the dominant part of the population.

In practice, it becomes an artist/yuppie duoculture within a decade :)

Isn't that a neutral statement by the OP? It seems objectively true, at least from my own limited experiences visiting SF twenty+ years ago and then again a few years past.

Speaking for myself I enjoy the company in limited doses. HN is fun to visit, but fuck me if I’d live here. There’s a big world full of perspectives and ways of thinking that would be concern trolled and rules lawyered to death by a group of techies. As monocultures go, tech isn’t terrible, but it’s still undesirable IMO. I do find the tech culture easier to swallow outside of the specific manifestation of SF/VC tech culture though. The more people over 40 around, the less it feels like a cult gone horribly wrong.

gay and hippie are cultures, tech is just a job

Hippie is a culture. You're right about tech tho.

Tech is also a culture. Tech people are generally rational, open to innovation, individualistic. HN is a good representation of the tech culture.
