Tesla's Cybercab/Robovan launch was an entertaining dog 'n' pony show in comparison, but set out the company's plans for fully autonomous robotaxis in detail. Neuralink wired up its second brain implant patient, Alex, who has been using the chip to play video games and operate CAD software hands-free.

Meanwhile, X Ai stood up the world's most powerful AI training supercomputer cluster, Colossus, building all the infrastructure and wiring up 100,000 nVidia H100 GPUs in a ludicrous 122 days start to finish. The company now has more GPUs at its disposal than Google AI, OpenAI, Meta AI, Microsoft or nVidia itself – and Musk says it'll have double the processing power within a few months thanks to 50,000 additional H200 GPUs.
