If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Thirty-five years ago, while Martin Amis was writing "Money," one of the novels that defined the nineteen-eighties, he admitted to a distracting dalliance with another contemporary icon. "I have spent weeks in a PacMan-fed stupor, unwilling and unable to think about anything else," he wrote in "Invasion of the Space Invaders," his "addict's guide" to the nascent arcade. Amis was not alone in his obsession. The Japanese-made game, in which players guide an auto-munching yellow head through a Daedalian maze, consuming a trail of pellets while fleeing four candy-tone ghosts, earned more than a billion dollars in quarters in its first year, surpassing the highest-grossing "Star Wars" film at the time. Pac-Man towered, Amis wrote, over "a vast garbage dump of rocky romances and wrecked careers."
My day job, in lieu of teaching creative writing like a normal person, is writing scripts for blockbuster video games. Last summer, while I watched a play-through of the then-unreleased Gears of War 4, for which I was the lead writer, something odd happened. The game's story called for a massive plane crash, out of which a single robot, operatically aflame, was intended to stride toward the player. Within the game's fiction, robots have hitherto opposed the player, but we wanted this particular burning robot to pose no immediate threat. The game programmers had thus switched off the hostility driven by the robot's artificial intelligence, allowing the player to walk past the hapless robot or shoot it.
The first time I met Alexa, the A.I. robot voice inside the wine-bottle-size speaker known as the Amazon Echo, I was at my friends' house, in rural New England. "Currently, it is seventy-five degrees," she told us, and assured us that it would not rain. This was a year ago, and I'd never encountered a talking speaker before. She's in cahoots with a sensor in their driveway.) When I razzed my friend for his love of gadgetry, he showed me some of Alexa's other tricks: telling us the weather, keeping a shopping list, ordering products from Amazon.
