Tesla's Director of AI is leaving the company

Tesla Director of AI, Andrej Karpathy, is stepping down from his role at the company and from the helm of its Autopilot program. "It's been a great pleasure to help Tesla towards its goals over the last 5 years and a difficult decision to part ways," Karpathy announced via Twitter on Wednesday, having just returned from a four-month sabbatical. The news follows suspicions, then confirmations, that Tesla would be reducing its workforce by as much as 10 percent. The company has already laid off more than 200 employees from the Autopilot division and permanently shuttered its San Mateo offices. Musk has previously made overtures about packing up and leaving Silicon Valley, where Tesla was founded, for the sun-baked shores of central Texas.
