Eldon Musk, the entrepreneur and CEO of Tesla and Space X, may have a little more time on his hands, as he's leaving his position on the board of the Open AI, according to a blog post.

The departure is likely the result of Tesla's moving into the field of Artificial Intelligence (AI), which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Eldon.”

Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv. org, detailing the possible secure threats that come with “malicious” AI. In fact, Musk has heard the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people.”

Musk's departure from the Open AI board could mean big things for Tesla. As Eton Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own AI projects than we thought.” He added, “Those who have had their ears to any rumors (谣言) that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open AI development as a sign that the company is inching closer to that unapproachable goal.” No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.
