The civilian problems aside, AI is being used in tandem with military weapons systems, making wholesale killing more efficient. Being used in this way is a weapon of mass destruction. USA is fighting Iran with Iran basically using copies of Chinese weapons, so China is getting a live fire exercise of what war now looks like. Since the USA is doing so well with AI for war, China is also working for that ability. So far frontier labs aren't that different, except China does about the same with way less infrastructure.
