1. Single men vastly outnumber single women in Silicon Valley due to the unfortunate gender demographics of the tech industry, making for a very competitive dating environment for single men.
2. Due to the Bay Area's high housing prices, single people living in the Bay Area who are not Bay Area natives tend to be highly-paid young professionals. These people tend to be driven, ambitious, and have very high dating standards. There's nothing wrong with having high standards, but it makes the dating scene more difficult since you have to work on meeting those standards in order to be successful with the dating scene. It seems like a man has to be in excellent physical shape, make a ton of money, and have the right pedigree in terms of degrees and credentials in order to be attractive in Silicon Valley since there are so many young professional single men in this area.
3. There's a big problem with "flaking" in the Bay Area, where some people have a bad habit of standing people up on dates and other social outings. This has happened to me, and it is very rude and inconsiderate, especially with the busy schedules that many people in Silicon Valley have, as well as the traffic.
4. This is probably my most controversial point, but despite the Bay Area's reputation as a politically progressive place, ethnic minorities seem to have a harder time dating than non-minorities. This matters to me since I'm black, a rarity in Silicon Valley. While the statistics on this page from OkCupid (https://theblog.okcupid.com/race-and-attraction-2009-2014-10...) are not confined to the Bay Area, based on my personal experience and on empirical research I've done by reading other sites regarding the dating scene in the Bay Area, it is a problem here.
To be frank, while I enjoy Silicon Valley's career opportunities, the high cost of living and the difficulties I've experienced dating here make me want to research some alternatives, although as a lifelong Californian (but not a Bay Area native), I'm a bit apprehensive about leaving the state since I enjoy California's diversity and weather. I've thought about Tokyo, which I've lived before as an intern and absolutely loved, but it would be a massive cut in salary.
