I’ve lived in SF since 2007. OP is likely factually accurate about where he lives, which is one of the worst blocks in SF. I’ll add that this was the case in 2007 as well, I wouldn’t say that 7th and Mission has gotten significantly better or worse over the years. It was likely slightly nicer when OP moved in, but that was the exception, not the historical norm.

The main thing is that OP then uses that to generalize about the state of the entire city. This makes it difficult to actually have a reasonable conversation about what is working and what isn’t in SF because everything reverts to the binary “sf is/isn’t a shithole” argument. In OPs case, it actually exposes the reality behind a lot of these “random tech blogger leaving SF” stories where they don’t actually know much about the city or appear to have much of a social life outside of tech that would expose them to other parts of the city. In SF there are tons of places to live that aren’t “single family homes 4 miles from downtown” - the city is 7x7 square miles.
