Ok that helps the issue in issue in 20-30+ years (develop the tech, start mass production, replace all old hardware with it) what can we do in this decade?

That is the government's problem, had they asked me 20 years ago, I would've told them moving all manufacturing operations to China just to enrich a small small percent of people would be disastrous for the nation.

Right now I don't care whether China or USA spies, they are identical countries in my mind.

Keep in mind that China can still spy on even with this Clean Network.
