Weapons makers have crossed into "troubling territory," says The New York Times.
They're developing weapons that use artificial intelligence to decide what to target and whom to kill.
Critics are worried that the weapons will become increasingly difficult for humans to control — or to defend against.
And they fear that weapons without human oversight could make war more likely, as easy as flipping a switch.
Others say automated weapons may result in fewer mass killings and civilian casualties. Autonomous weapons, they say, don't commit war crimes.
Representatives from "dozens" of nations will meet on Thursday in Geneva to consider whether development of robotic weapons should be restricted by the Convention on Certain Conventional Weapons, the Times says.
