All those jobs in Detroit that went away were replaced by…? As best I can tell they were replaced by poverty and crime.
It's more an example of how racism and reliance on singular industry can quickly create pits that are largely insurmountable. Similar cases can be found in coal country in Appalachia. The lesson isn't to prop up local industry to maintain job and economic stability. The lesson is to stage out disruption. ILA recently took this on with automation in shipping. The goal isn't to prevent automation but to not give companies a blank check to mass fire workers and replace them with automation.

We've been at it for more than a century now and it seems to be working pretty well for nearly everyone!
Our goal is not to preserve jobs. Our goal is to be more productive for fewer resources.
Jobs in Detroit went away - but so did the people, who found new jobs in other cities. There has been no lasting unemployment from automation, ever.
Human beings are good for more than pulling levers and carrying heavy objects and we do each other a disservice by pretending otherwise.
Do you have some citations? There’s absolutely no indication they “found new jobs in other cities” but there is plenty of proof they just never found another well paying job and moved into welfare or became homeless.
That would not be the case if they "moved into welfare" or became homeless.
You seem to have the idea that welfare systems in US cities can handle 40% of the city becoming jobless. I assure you this is not the case.
Unless you're trying to convince me that several hundred thousand people just died, they very obviously moved out.
I can't prove that Detroiters specifically all found better paying jobs, but there is ample evidence online that shows that the real factor crushing the middle class is the sheer number of Americans being catapulted upwards.
Most cutting edge technologies like advanced rocketry are not requirements for a century- to millenium-scale survival at all-around medieval technology level.
