It’s not a good look when your technology is replicated for a fraction of the cost, and your response is to smear your competition with (probably) false accusations and cozy up to the US government to tighten already shortsighted export controls. Hubris & xenophobia are not going to serve American companies well. Personally I welcome the Chinese - or anyone else for that matter - developing advanced technologies as long as they are used for good. Humanity loses if we allow this stuff to be “owned” by a handful of companies or a single country.
