Who is going to regulate the US and Chinese militaries? The CEO of Palantir just published an open letter calling for a Manhattan Project for superintelligent AI warfare.

What needs to be regulated is the performance of the hardware designs. I have not seen anyone except for myself specifically say this. And no one listens to me. So it seems that society may not figure that out until it's too late.
Western militaries have justice systems, including courts and prisons. I presume they also follow best practice in lots of domains, despite some legal exemptions. They also clearly have the aim to preserve society in a safe state.
Even if militaries are outside the remit of these new AI orgs, they could still be useful in the civilian world.
