Tesla's chip technology and Dojo supercomputer development efforts are facing a leadership change as Pete Bannon departs the company. Bannon, who previously worked at Apple, joined Tesla in 2016 and played a key role in advancing Tesla's in-house chip design and supercomputing capabilities. The departure raises questions about the future direction and timeline of these critical projects, as Tesla aims to reduce reliance on external suppliers and enhance its AI and autonomous driving technologies. Tesla has not yet announced a replacement for Bannon.
