Expecting companies to build their own chip foundries and manufacture their own chips to avoid tariffs is as unrealistic as expecting poor people to singlehandedly use nuclear fission to create atoms from nothing to materialize into existence all the food they can’t afford. Even if these American “use AI for everything” megacorp regimes that can’t even write a mouse driver that’s under 1gb actually put their big swingin’ dicks back into their pants long enough to actually figure out how they could be efficient enough use the more achievable 90nm and 65nm chips, even that is so unachievable they’d never find a way to mass produce them affordably. Russia supposedly managed to diy their own 350nm chips which is barely even mid 90s Pentium 1 era bullshit and even that’s probably fake propaganda that, best case, followed some half successful low volume experiments in a lab.
