Forget Skynet. Humanity may be fucked by a simple AI error. From WSJ:

“….There are no established methods to test AI for safety, fairness or effectiveness. Error-prone or biased artificial-intelligence systems have the potential to taint our social ecosystem in ways that are initially hard to detect, harmful in the long term and expensive—or even impossible—to reverse. And unlike public infrastructure, AI systems are largely developed by private companies and governed by proprietary, black-box algorithms.”

Byeeeee.
