As I remember, North Beach in particular did become unaffordable at about that time. Other parts of The City remained expensive but affordable up to the 2000s.

The rent jumps and illegal/shady evictions starting maybe 2010-2012 effectively pushed out a fraction of those surviving on rent control plus many of the merely upper-middle-class out of the city, leaving the wealthy and big-5 programmers getting huge salaries for 80-hour-days during the whole of the best years of their lives.

The thing about the situation the city hasn't "upgraded" but rather has been left gray and boring (yet fearful and hyperkinetic). Pretty sad compared to the lively punks I saw squatting old industrial buildings in 1984. Even that was sad compared to the summer of love I assume but I wasn't around for anything but the end of that.
