Elon Musk unveiled Macrohard (or Digital Optimus), a joint xAI-Tesla project with the potential to replace every computer-related job in the world. Macrohard will combine Grok as the brain, Optimus as the digital worker following commands, Tesla's cheaper hardware and Nvidia's costlier hardware. "In principle, [Macrohard] is capable of emulating functions of entire companies," Musk said.
