I had always thought the supposed end of automaker dominance Detroit-style doomsday scenario was impossible for S.F., but turns out the normalization of remote work was all it took. The American software industry didn't need to end, it just had to go home.
NYC is doing great, as are quality-of-life focused cities like KC, Miami and Columbus. Maybe calling every critic in your town names and letting QoL go to absolute crap is the real driver of movement.
The comparison to Detroit seems apt. When the automakers scaled down, there was no "Plan B" and the city leaders were too incompetent/corrupt to actually lead.
