That doesn't describe SF in the least.
OP said this is how cities die, my point is there's a type that is more at risk, and most U.S. cities are that type.
Grandparent said "this is how cities die" related to remote working and emptying the downtown core - as is happening SF.
You then said "This is how cities -- cities without commercial on street level and residential above, cities where you need to own a car -- die."
The topic is San Francisco. So am I to read your comment as completely unrelated to the topic at hand?
At least that's what Terretta is saying. I haven't even visited SF in over a decade, so I don't know what its current situation is like.
