To be fair, a lot of it is moving to drones killing drones.

My prediction is that future wars will actually involve increasingly fewer humans and will be more about tech+manufacturing vs. tech+manufacturing. And of course insurgents + lowcost tech vs. increasingly nonlethal hightech.

This would allow wars to continue without as much of the growing political backlash.

The next iteration is the drones removing those pesky humans from the command chain too :/
