Big tunneling milestone! For the first time, TBC has continuously mined in a Zero-People-in-Tunnel (ZPIT) configuration. There is nobody in the machine (besides the videographer), which is simultaneously advancing forward and erecting a ring (i.e. building the tunnel). Each full ring weighs ~24,000 pounds. In the same way that full and rapid reusability is the holy grail for rockets, ZPIT continuous mining is the holy grail for Boring Machines. This is the safest, fastest, and least expensive architecture to build tunnels.




@MarketsnCharts @wholemars lol Tesla 2x’ed after you predicted “nothing but down hill from here”

I left xAI earlier this week. It was a difficult decision. The past two years have been an intense, fun, and deeply rewarding journey, and I accomplished things I could not have imagined two years ago. Thank you @elonmusk for the opportunity and for everything I learned at xAI. Thank you @Guodzh for the trust you placed in me and for all the days and late nights we worked through together. And thank you to the entire Omni / Imagine team: thank you for your trust, and for growing together with me. It has been an honor, and I am incredibly proud of what we achieved together. I feel fortunate to have had the chance to work with all of you. At xAI, everything feels possible. I had the chance to work with and learn from some of the most exceptional people I have ever met. I was able to explore across domains: from pretraining to post-training, from language models to multimodal, from perception to generation. Joining xAI was one of the best decisions I have ever made. @grok imagine is special to me. Building video generation models, where I started with almost zero prior knowledge, from 0 to No.1, as an IC and as a lead, alongside an extraordinary team, and shipping it as a great product used by millions, all within 6 months, at age 28: I feel proud. But now it’s time for me to move on. I’m burnt out, and I know my happiness is no longer maximized in my current state. It is sad to say goodbye, but it is just the right time for a change. Best wishes to the Imagine team, you are absolutely the best, and you deserve the best. I will cherish all our memories for the rest of my life. For now, I’m taking a break and giving myself time to figure out what comes next. Posted from Hawaii.

@the_transit_guy Now do cost per passenger when you see the prevailing cost for a people mover ($3b at LAX)
