Foot, Point, shoot.
You have to wonder who is responsible for US foreign policy these days, and if they have ever had to do any planning beyond the next quarter.
The US gov tells US companies that they can't sell their chips to China. Why? So China can't build a more powerful super-computer then the US. What did they think would happen next? Did they really hope that China would just kowtow and give up trying? Have they ever done that before? So China did exactly what China always does and learnt how to build the chips it needs itself. Now it no longer needs to buy any US made chips for its super-computers. And guess what? It longer needs to buy US made chips for its ordinary computers either. And because it will make so many, it can sell them to anybody else who wants them for less then the US companies can sell them. I wonder just how long the US chip industry has left? And more importantly, what act of incredible stupidity will the US try next to 'save' the US chip industry?
Talk about short-sighted! Should have gone to spec-savers!
