Too many people in the desert using too much water. Farming is the biggest culprit. A long time ago they made a plan to distribute the water but they gave away too much even then. The problem has become worse because there hasn't been enough rain in the region for, like, a decade. Now unless people agree to stop using water the place could become uninhabitable, at least for the number of people who want to live there.

That's horrible. Do it again

Either we are talking about remote controlled robots, like predator drones or we are talking about fully autonomous systems. The question is what job we think is better served by the robots.

Robots work as bombers because people and the stuff necessary to keep them alive are heavy and a plane functions much better without us sitting in it.

A robotic dog isn't really any better in most situations than just a dude, or a regular dog. It is going to require a power grid and maintenance while soldiers just require food, bullets, and water.

AI on the other hand is more interesting. It can notice patterns humans don't and it can potentially make choices and act far more quickly than a human can. One space I think this might be helpful is in point defense. If the AI could recognize car bombs or suicide bombers it could act to neutralize the threat before the guards are even aware of it.

Fork lifts exist because humans are weak, AI exists because people are stupid and expensive. Where can AI either outperform or undercut a human?

Do you think you could train an AI vision algorithm to recognize people with concealed weapons? What about suicide bombers?

You could use it arbitrarily to clear an area, but it certainly won't be any more effective than a tomahawk missile at the same job. We've all seen those videos where a robot flicks the unripened cherries out of the air, are we imagining it doing the same with people? Letting the good ones pass while delicately cutting the rest down with a burst of gunfire? Facial recognition technology functions worse the darker your skin is, which is unfortunate due to the number of brown people we like to target with these weapons. I don't imagine these will see a lot of use in Western Europe

Actually, no, Twix can't exist in superposition. They compress to antimatter when unobserved.
