It's largely a different list; but importantly, it's not an entirely new list. San Francisco was a wealthy city in 1949 and it remains one of the wealthiest today. But could that be changing? Given the city's current challenges, some are questioning whether it might end up as another Detroit.

I don't see that happening. And for what it's worth, here's evidence of nearly 75 years of resiliency.
