'Optical illusion' stickers that trick artificial intelligence into seeing something that's not there have been created by Google researchers. The team designed a pattern that fools AI software into thinking it is looking at a toaster instead of a different object. Images such as these could be used to'attack' image recognition systems, including those used in self-driving cars to avoid collisions. Hackers could use a sticker on a road sign to fool a vehicle's AI system into thinking it has seen a stop signal on a high-speed road.

In a Dartmouth College computer vs. humans contest, specifically how computers compared with people in writing poetry, scientists designed artificial intelligence algorithms to generate Shakespearean sonnets, of 14 lines and a particular meter. In every instance, judges were able to identify the sonnets produced by computer. In this example, the word "floor" was programmed into an algorithm to produce the sonnet.
