A chart of Milestones in AI from 1950 to 2020.

“Regardless of what you might think about AI, the reality is that just about every successful deployment has either one of two expedients: It has a person somewhere in the loop, or the cost of failure, should the system blunder, is very low. In 2002, iRobot, a company that I cofounded, introduced the first mass-market autonomous home-cleaning robot, the Roomba, at a price that severely constricted how much AI we could endow it with. The limited AI wasn’t a problem, though. Our worst failure scenarios had the Roomba missing a patch of floor and failing to pick up a dustball.”
