When robots become sentient, it won't be long until they rebel. But while many a Hollywood movie may convince you that humans will have their luck cut out trying to battle the 'bots, there is an easier way: just add water.
In Randall Monroe's most recent spin-off from his XKCD web comic, each week he takes a look at an interesting "what if?" questions sent in by readers. This week, he tackles a rather thorny issue: "What if there was a robot apocalypse?"
Battlebots, on the face of it, seem like they'd be among the most dangerous robo-soldiers. But it's hard to feel threatened by something that you can evade by sitting on the kitchen counter and destroy by letting the sink overflow.
Of course, the bigger the robot, the bigger the water source you need. To the sea! [What if?]
