The Ishikawa Oku Lab's high-speed Janken robot hand wins every single game of rock, paper, scissors it plays.

No, it doesn't read its human opponant's mind — not yet at least. It wins by cheating really fast. Too fast for humans to notice.

IEEE Spectrum elaborates:

It only takes a single millisecond for the robot to recognize what shape your hand is in, and just a few more for it to make the shape that beats you, but it all happens so fast that it's more or less impossible to tell that the robot is waiting until you commit yourself before it makes its move, allowing it to win 100% of the time.

The folks at Ishikawa Oku Lab say the technology behind their robot can be used to reduce the time delay of human-robot work cooperation, but I say they've doomed us all.
