alt Hacker Newsthe number of functioning machine shop in the US in large urban areas has been plummeting for decades. where there were 50 there are now 3. the customers for machine shops are large production facilities with a need for custom parts. they're all gone. now its little bits of rnd work and some custom architectural design kind of stuff. and the margins are punishing.
ok, so machine shops aren't really central to the argument, but the collapse of demand is.

Kinda. What's the lead time on my high precision metal part that needs to be cut on a 6-axis lathe? Or a metal 3d print? Neither of those machines are cheap, so not only is lead time astronomical, profit on them is also pretty great for the machine shop, which implies there's room for more machine shops. There's a lot of red tape for the orders I see, (CMMI etc) so maybe AI will help machine shops get that and be competitive.
They're all gone completely, or gone as in moved to where they don't have to suffer ridiculous real estate costs? There are approximately 50 machine shops within a stone's throw of my place out in the middle of nowhere. I haven't been around long enough to truly know if that is more or less than the historical norm, but best I can tell it is a growing sector locally.
