The tiny changes that can cause AI to fail

The car comes to a stop sign it's passed a hundred times before – but this time, it blows right through it. To you, the stop sign looks exactly the same as any other. But to the car, it looks like something entirely different. Minutes earlier, unbeknownst to either you or the machine, a scam artist stuck a small sticker onto the sign: unnoticeable to the human eye, inescapable to the technology. The tiny sticker smacked on the sign is enough for the car to "see" the stop sign as something completely different from a stop sign.
