US lawmakers propose ban on AI in nuclear missile systems.

US Senator Edward Markey and Representatives Ted Lieu, Don Beyer, and Ken Buck have introduced bipartisan legislation that would prohibit the use of federal funds for launching any nuclear weapon by an automated system without "meaningful human control." The Block Nuclear Launch by Autonomous Artificial Intelligence Act aims to codify the US Department of Defense's policy that only human beings can authorize the employment of nuclear weapons into law. The bill is part of a larger plan to reduce the risk of "nuclear Armageddon" and hinder nuclear proliferation.
