In the very near future, the world's militaries will be incorporating even more robotic and AI tech into their armaments, including face tracking drones with weapons, robotic exoskeletons and robots with guns. Ideally, we'd be able to remove humans from combat, and even turn wars into video games - but that's unlikely to happen. Countries that spend the most money on their militaries will also use these new killing machines to change the rules of engagement. It's not pretty, but it is the future of war.
