Tesla is shutting down Dojo, the supercomputer project that was at one time key to the automaker's driverless-vehicle technology. Dojo's head is also leaving the company.

Weeks after Elon Musk promised investors that Tesla’s Dojo supercomputer would be “spectacular” and operating at scale, Bloomberg says the project is shut down, raising sharp questions about his credibility.

The disbanding of Tesla’s Dojo efforts follows the departure of around 20 workers, who left the automaker to start their own AI company dubbed DensityAI focused on data center services for industries.
