@savedsinner777 SF definitely has downsides; was not a fan when I first moved from Texas (my car was stolen in the Filmore Center). It depends on what you are doing, where your customers are, your financial situation, etc. Definitely, tailor the advice to your situation esp if you are getting from someone on the internet (who's giving the advice, their motives, are they targeting people like your or someone else?).
HOWEVER in general, if you are starting a startup, which is an incredibly lonely and difficult journey fraught with constant rejection and failure, there is a hub of smart and driven people doing something very similar. And they are all within a few mile radius in SF. And many of them are also early adopters of new technology/products. And there are investors/accelerators who are open to giving money to a shitty pre-seed company. Being in SF is part of a recipe for creating opportunity for yourself.
