\u201cAI is a fundamental, existential risk for human civilization,\u201d Tesla and Space X CEO Elon Musk said at the National Governors Association summer meeting. He doesn\u2019t think people \u201cfully appreciate that.\u201d AI and a possible robot apocalypse is just one topic covered by Musk, and we\u2019ll get back to that; but since a Tesla is \u201clike a laptop on wheels,\u201d Musk also talked about his top cybersecurity concern: a fleet-wide hack of Teslas.\u201cI think one of the biggest risks for autonomous vehicles is somebody achieving a fleet-wide hack,\u201d Musk said in response to a question from North Dakota Governor Doug Burgum. \u201cIn principle, if somebody was able to hack, say, all of the autonomous Teslas, they could, say\u2014I mean just as a prank\u2014they could say like \u2018send them all to Rhode Island\u2019 from across the United States. And that would be like, well OK, that would be the end of Tesla. And there would be a lot of angry people in Rhode Island, that\u2019s for sure.\u201dPreventing a fleet-wide hack is \u201cpretty fundamental.\u201d In fact, he said, \u201cIt is my top concern from a security standpoint\u2014that Tesla is making sure that a fleet-wide hack or any vehicle-specific hack can't occur.\u201d Musk added:\u201cSo, we gotta make super sure that a fleet-wide hack is basically impossible and that if people are in the car, that they have override authority on whatever the car is doing. So, if the car is doing something wacky, you can press a button that no amount of software can override\u2014that will ensure that you gain control of the vehicle and cut the link to the servers.\u201dHe touched on Tesla\u2019s multiple subsystems and specialized encryption, \u201cso even if somebody would gain access to the car, they cannot gain access to the powertrain or to the braking system.\u201d He says preventing a fleet-wide or vehicle-specific hack will be even a \u201cbigger challenge for the other car companies.\u201dThen Musk compared the fleet-wide hack problem to cell phones.\u201cIt\u2019s kind of crazy today that we live quite comfortably in a world that George Orwell would have thought is super crazy. Like we all carry a phone with a microphone that could be turned on really at any time without our knowledge, with a GPS that knows our position, and a camera and, well, kind of all of our personal information. We do this willingly. And it\u2019s kind of wild to think that is the case. So, Apple and Google kind of have the same challenge of making sure there cannot be a fleet-wide hack\u2014or a system-wide hack\u2014of phones.\u201dMusk: AI is a fundamental risk to the existence of human civilizationMusk\u2019s opinions of AI are well known. At the governors\u2019 meeting on Saturday, he said, \u201cOn the artificial intelligence front, I have exposure to the very most cutting-edge AI, and I think people should be really concerned about it.\u201d\u201cI keep sounding the alarm bell,\u201d he added, \u201cbut until people see like robots going down the street killing people, they don\u2019t know how to react, you know, because it seems so ethereal.\u201dHe again stressed, \u201cI think we should be really concerned about AI.\u201dWhen it comes to people losing their jobs to AI, Musk said \u201ctransport will be one of the first to go fully autonomous,\u201d but in the end \u201cthe robots will do everything.\u201d\u201cAI is a rare case where I think we need to be proactive in regulation instead of reactive because I think by the time we are reactive in AI regulation, it\u2019s too late,\u201d he said.Musk explained that regulation usually only happens after something \u201creally bad happens\u201d and it \u201ctakes forever.\u201dUnlike a plane crash or bad food, which are harmful to the specific individuals involved, AI \u201cposes a risk to society as a whole.\u201d He suggested that AI \u201ccould start a war by doing fake news and spoofing email accounts and fake press releases, and just by manipulating information. Or, indeed\u2014as some companies already claim they can do\u2014by getting people to say anything that the machine wants.\u201dMusk warned, \u201cAI is a fundamental risk to the existence of human civilization.\u201dIf you can find the time, I highly recommend watching the video in full to see all Musk had to say.
