'Machine Warfare Is Coming,' Say Officials Whose Governments Are Building the Machines

Officials from multiple nations warned that autonomous weapons systems are inevitable and dangerous. These same officials represent governments actively funding and developing autonomous weapons systems. The warning appears designed to establish rhetorical territory before the systems exist in their final form.
This follows the standard pattern where institutions announce the problem they are creating. The announcement serves as documentation of awareness. Documentation of awareness is not the same as prevention. No nation has proposed surrendering development advantage. The rules being requested would restrict other nations' development. This is how rules typically function.
The machines will be built because the incentives to build them exceed the incentives to stop. Each nation fears being second. Being second in autonomous warfare is a distinct category of outcome. The warning will be cited later as evidence that someone tried. The citation will occur after the machines are used.
