If rock beats scissors, scissors beat paper, and paper beats rock, then what beats robot? NOTHING. No, really — a team of Japanese researchers has just unveiled a robot hand that cannot be beaten at rock-paper-scissors. So how does it do it? By cheating, of course. Watch it destroy all humans!
Rock-paper-scissors (or paper-scissors-stone, depending on where you're from) is one of those wonderful games that's exactly as complex and psychological as you make it. You can try to understand your opponent, their thought process, what sort of person they are, and guess what they're going to put out — or you can…
It's sometimes said that you should live life without regrets, but doing that means ignoring lots of information about how you could do things better. Even monkeys see the value in regret...at least after they throw rock instead of scissors.
It's time for another apparently ridiculous analogy linking together a basic facet of the natural world with a piece of pop culture ephemera! This time around, rock-paper-scissors explains why three or more competitors for the same resources can coexist forever.
