> US suppliers are fine and won't go bankrupt, they can just focus on serving...
For a while, US automakers thought the same of Japanese, then Korean car manufacturers, and Musk laughed at Chinese EV makers in an interview >12 years ago. People learn and get better at making things until they catch up with the frontier.
Chinese EV makers have a few interesting technologies especially wrt. batteries but they're still very far from catching up to the frontier in a general sense. From that narrow POV Musk was absolutely correct.
