Mark Zuckerberg has "thrown shade" at Elon Musk before regarding Musk's wariness of artificial intelligence, most recently on Sunday. On Tuesday, the Tesla founder threw some shade of his own right back. Musk is concerned that artificial intelligence could someday threaten humanity, possibly becoming more dangerous than nuclear weapons, but Zuck said Sunday during a Facebook Live video that he thinks AI is promising and "people who are naysayers and ... try to drum up these doomsday scenarios ... I don't understand it. It's really negative, and in some ways, I actually think it's pretty irresponsible." Musk's response was short and sweet: "I've talked to Mark about this," he tweeted. "His understanding of the subject is limited."
Per Zuck, while technology can always be used for good or bad purposes and those who build it need to be careful, it's "questionable" to argue for slowing down the development of AI. "If you're arguing against AI, then you're arguing against safer cars that aren't going to have accidents, and you're arguing against being able to better diagnose people when they're sick," the Facebook founder said in the video, as reported by Business Insider. Expect more from Musk soon; also Tuesday on Twitter, he teased a "movie on the subject coming soon." TechCrunch (which has a piece up Tuesday insisting AI "is not as smart as" Musk thinks) notes that the founding director of MIT's Computer Science and Artificial Intelligence Lab has said Musk's understanding of AI is limited.
