They're not building jet engines yet either. The higher up the value chain, the more difficult things are. And that pole keeps getting higher every year. So it's not a matter of 'catching up' - it's 'catching up and then getting ahead and staying ahead'. And, that pathway is quite some time. I'm not sure the factories themselves are hugely relevant, because with all of he talent, supply chain and operational issues and know-how scrambled up, it'd take them forever to get it back up. Those fabs would be a bit of a write off no matter what.
