> What has made the auto industry particularly vulnerable is its reliance on just-in-time delivery, where parts are brought in when needed, rather than being stockpiled.

This idea has gotten a lot of play lately. But the unstated alternative is to somehow perfectly forecast future demand for parts. That's very difficult in general and doubly difficult during a global pandemic. And, in fact, well-practiced lean outfits are better at knowing which inputs are potentially most disruptive, because they already obsess over lead times for everything.

Without lean practices you just wind up with giants piles of almost random inventory. That you'd have wound up with a giant pile of CPUs is a total crapshoot. But you would absolutely positively have a bunch of stuff you don't need and never will. And that inventory would choke the whole company to death.

The whole idea that JIT destroyed some glorious, flawless past is the Nirvana fallacy. "Oh, supply chain disruptions happen at all, therefore JIT is entirely useless". It's just a silly idea and needs to be mocked at every opportunity.
