Ignoring the cost of wages, the logistics are impossible.
1.) It takes about 7 years to make a world class chip factory like TSC, Pegasus, Nvidia, Foxconn.
2.) the machines that make chips are built in Taiwan, which won’t exist if China invades. Hell, most good manufacturing lathes and mills are made there as well.
3.) The transformers and power distribution to power said factory are 5 years backlogged today and come from China.
If China takes over Taiwan, we will be forced into WW3 to fight to the last man or we can be choked off and thrown into the Stone Age.
It would take us 15 years to recover technologically if China abruptly invades Taiwan. During those interim years we would stagnate, unable to manufacture numerous goods, computers for vehicles, airplanes, industry, etc.
It's a very dangerous concentration risk.
