Elon Musk is pushing ahead with supercomputers to enhance Tesla and xAI. Tesla is investing $500 million in its Dojo supercomputer in Buffalo and building another in Austin. These will process data from Tesla’s cars to improve Autopilot and Full Self-Driving systems. Musk believes Dojo will help Tesla reach full autonomy, crucial for robotaxi success. Musk also plans to use Dojo for Tesla’s humanoid robot, Optimus, and is building a separate supercomputer for xAI’s chatbot Grok.
