It can be a boon if a balance is achieved, where Nvidia chips are used as a pacing function for domestic chip companies, similar to Tesla was for domestic EV. Like Tesla, there should also be an expectation of Nvidia making the chips in China if they wish to stay long-term, helping up level domestic chips manufacturers and software developers.
