Perhaps a humorous example of this: a robot that always wins at rock paper scissors: https://www.youtube.com/watch?v=3nxjjztQKtY https://www.youtube.com/watch?v=3nxjjztQKtY There's a fun parlor trick which takes advantage of human reaction time too: place a hundred dollar bill on the table, let the other party place their hand a few inches away, start your hand a foot above theirs; the first person to place their hand on the money wins, and the other party can start moving as soon as you start moving. Turns out you can easily go around their hand and grab the bill before they're able to react.
