Before we get to the whole robots-are-thinking-for-themselves-and-they’ve-come-to-kill-us deal, we’ve got a lot more help to get from modern-day technology. One of these helpful AI systems is the new iRobot Looj 330 Gutter Cleaner ($300), which helps, not harms, humans by getting in their gutters and tearing through leaves, dirt and clogs with the press of a button. The Looj has enough of a brain to travel down your gutter on its own and adapt to the debris, but not enough to say, slit your throat as you sleep.
