Tesla said last night Chris Lattner, the vice president of Autopilot software, has left the company about six months after the electric car-maker hired him away from Apple. From a report: Lattner had led the software development team in charge of Autopilot. Tesla executive Jim Keller is now in charge of Autopilot hardware and software. The company announced it had also hired OpenAI research scientist Andrej Karpathy, who will serve as Tesla's new director of artificial intelligence and Tesla Vision. "Chris just wasn't the right fit for Tesla, and we've decided to make a change," the company told reporters in a statement. "We wish him the best." Lattner tweeted last night, "Turns out that Tesla isn't a good fit for me after all. I'm interested to hear about interesting roles for a seasoned engineering leader!" Lattner is a widely respected figure in the industry. He is the main author of LLVM as well as Apple's Swift programming language. We interviewed him earlier this year.
