And yet there seems to be shockingly little effort towards making sure that doesn't happen. Why isn't there an underground bombproof chip fab somewhere?

It's like as if people don't really care about technological society, they just do what they always do, expand and try to do stuff that is hard and impressive, and if the computers went away... they'd be just as happy as a blacksmith or something...

Or maybe even happier.

A modern chip fab needs a supply chain the size of humanity. And you can't bury a reserve humanity in case the regular one goes bust. A buried chip fab would be scrapped for steel.
