&quot;There are few middle-aged and effectively no old people there&quot;.<p>Well that&#x27;s just total bullshit. There are tons of middle aged and elderly people in SF, most of whom moved to the city in the 60s or 70s and bought property before it became ridiculously expensive. There is a huge population of aging hippies still in SF. Now if you mean &quot;there are few middle aged people working in the startup world&quot;, you might be correct, but I&#x27;d guess that&#x27;s the same for startups anywhere.<p>Not everything in San Francisco is the tech world, and the city does not just consist of the Mission and SOMA. Most of the city is non-tech families and less exciting residential neighborhoods. People who dont live in SF usually dont see that side of it.
