It seems like every week we hear about more humans losing their jobs because of automation (read: robots). How can a human that expects pay possibly compete with machine slave labor? The answer is in banking.
Thanks to ATMs, the only reason people actually walk into a bank anymore is to rob it, but a bank teller in Detroit was having none of it. According to reports, a man walked into a bank in suburban Detroit and handed the teller a note saying that he was armed. The bank teller simply walked away, forcing the would-be robber to leave empty-handed.
The inefficiency of the American worker thwarted a bank robbery. Meanwhile, you can empty an ATM with nothing but a drill and a gadget you can make for $15. We win this round.
