Musk’s xAI loses second co-founder in two days as Jimmy Ba departs https://www.cnbc.com/2026/02/10/musks-xai-loses-second-co-founder-in-two-days-as-jimmy-ba-departs.html
I resigned from xAI today. This company – and the family we became – will stay with me forever. I will deeply miss the people, the warrooms, and all those battles we have fought together. It’s time for my next chapter. It is an era with full possibilities: a small team armed”” https://x.com/Yuhu_ai_/status/2021113745024614671
Since xAI was formed just 30 months ago, the small and talented team has made remarkable progress. The future has never looked more exciting!”” https://x.com/xai/status/2021667200885829667?s=20

.@elonmusk told me he plans to build “Optimus Academy” to train an army of humanoid robots. > “millions of simulated robots in the simulated world” > “tens of thousands of robots in the real world, to close the simulation to reality gap.” Why? There’s two big differences”” https://x.com/dwarkesh_sp/status/2019513611002007717
As I was preparing to interview Elon, I put together some notes to help me think through orbital datacenters. Turned them into a blog post. Please take them with grains of salt so big you might confuse them for rocks.”” https://x.com/dwarkesh_sp/status/2019479454054248815
Elon : For Optimus, it’s difficult to match the flywheel of the existing vehicle fleet. The plan is to build a fleet of 10k-30k robots to perform self-play and testing. Millions of robotic agents will train in Tesla’s “”reality generator”” (simulation), the real robots can then”” https://x.com/TheHumanoidHub/status/2019479864525611472
Elon explains why Optimus will cost more than smaller, non-intelligent humanoid robots like those from Unitree.”” https://x.com/TheHumanoidHub/status/2019842414501093776
Elon Musk suggests spate of xAI exits have been push, not pull | TechCrunch https://techcrunch.com/2026/02/13/elon-musk-suggests-spate-of-xai-exits-have-been-push-not-pull/
Elon says Grok will orchestrate Optimus robots; for instance, by coordinating a fleet to construct an entire factory. He refused to comment on the merger of xAI and Tesla.”” https://x.com/TheHumanoidHub/status/2019473047733039353
Elon: – SpaceX will launch more AI (compute) than the cumulative amount on Earth of everything else combined. – Most AI will be inference; already, inference for the purpose of training is most of training.”” https://x.com/TheHumanoidHub/status/2019468740346212805
For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to”” https://x.com/elonmusk/status/2020640004628742577?s=46
The first question I asked @elonmusk: What’s the point of sending GPUs into space? The whole idea behind orbital data centers is that if the launch costs continue to drop, it will become cheaper to put GPUs in orbit than to build power plants on Earth. The problem with this”” https://x.com/dwarkesh_sp/status/2019499174384005458
