How Much You Should Worry About Tech, From AI to Hacked Nukes

Technology is transforming our lives so profoundly, so quickly, that it can be scary. We asked experts to weigh in on how much we should be stressed about self-driving cars, rogue nuke launches, evil AI, and more. You can loosen your white-knuckled grip on the steering wheel. In cities where self -driving cars are being tested on public roads--San Francisco; Boston; Tempe, Arizona--there's a trained engineer on board to make sure the nascent tech doesn't start taking out squirrels (or pedestrians). "It's that person's job to pay attention to what the vehicle is doing," says Nidhi Kalra, codirector of the RAND Center for Decision Making Under Uncertainty.
