> Am I wrong in assuming that if U.S. doesn't develop this tech some other country will? You are not wrong. Alibaba, Baidu, etc. work heavily with the Chinese government in this area.
Is that the old tired "if you won't help build tools to butcher people, evil chinese will?" argument? This zero-sum, jingoisti, outlook on the world has caused most damaging and bloody wars in history. World policy is not a zero sum game and every human does not have to help kill other humans for the world to be at peace.
The Pentagon does not deal in World Policy, it deals in martial policy. As General Mattis said, "If you don't fund the State Department fully, then I need to buy more ammunition ultimately".
