“AI is a fundamental, existential risk for human civilization,” Tesla and Space X CEO Elon Musk said at the National Governors Association summer meeting. He doesn’t think people “fully appreciate that.” AI and a possible robot apocalypse is just one topic covered by Musk, and we’ll get back to that; but since a Tesla is “like a laptop on wheels,” Musk also talked about his top cybersecurity concern: a fleet-wide hack of Teslas.

“I think one of the biggest risks for autonomous vehicles is somebody achieving a fleet-wide hack,” Musk said in response to a question from North Dakota Governor Doug Burgum.
