I guess I am a somewhat neutral bystander here. I'm from India and the way I see it, these sorts of actions, will simply force China and Chinese companies to develop alternatives to US products. For the short to medium term these blacklists will hurt Chinese companies severely, perhaps even put some of them out of business. However, in the long term 15-20 years, I would imagine, China would have fully caught up with the US particularly on semiconductor design and fabrication. Once that happens, the dominance of the US tech stack will start to falter and eventually erode away. If I were the US govt., I would invest every available dollar and minute on building up a technological lead, because, oh boy it is going to need every last bit of advantage it can get. And even that may not be enough.<p>For the world, this may not be a terrible outcome, (although don't get me wrong -- no trade war would be the best outcome.) . For one thing, it breaks monopolies across the tech stack from E-commerce all the way to semi-conductor manufacturing equipment. That competition between US and Chinese companies can only benefit the world. It's happening in 5G already.
