16 years of relentless engineering in one video. From SpaceX’s first Falcon 9 launch in 2010 to the 700th Falcon launch today. Both lifted off from the same pad, SLC-40. From proving Falcon 9 could reach orbit to making reusable launches look routine. Congratulations SpaceX!

Commit yourself to these seven virtues: Honor, strength, courage, duty, justice, beauty, and truth.

Eight years ago, Elon Musk said: “Mark my words: AI is far more dangerous than nukes.” Elon didn’t give in to the AI doomers. In fact, his position is very different from theirs. He has warned about the risks of AI for years while still pushing for its development, with a strong focus on safety. His view is that companies should build powerful AI, but do it safely and responsibly, even if that means slowing the pace when necessary “I think the danger of AI is much greater than the danger of nuclear warheads by a lot and nobody would suggest that we allow anyone to just build Nuclear warheads if they want that? That would be insane. And Far.”

Grok Build just got another update focused on making multi-agent sessions easier to read and navigate Subagent groups now clearly show how many agents are still running versus finished, dashboard search and resume selection behave more predictably, cancellation banners show the actual cause, and long paths are cleaned up across headers and dashboards MCP handling also gets a useful fix....tools with long server prefixes are no longer silently dropped Another small release that makes busy agent sessions much easier to understand at a glance Release Notes: v1.0.31 Bug Fixes: • Folded subagent groups in scrollback now correctly label how many are still running versus completed. • Dashboard search and the resume picker now clearly indicate the active text field and restore list selection after search. • Dock sections no longer keep a selection highlight after you collapse them with a click. • Worktree paths no longer show an extra suffix in the header or dashboard. • MCP tools with long server prefixes are now kept instead of being silently dropped. • Turn cancelled banners now correctly name the cause instead of always saying "by user". • Long paths in headers are now always shortened to the last two components

700 Falcon flights completed. Congrats to the SpaceX Falcon team!

Tesla Model 3 achieved 5-star safety rating in all categories!

Named my grok bot after the sentient AI, Jane, in speaker for the dead. I look forward to when I can sub-vocalize like Ender to communicate with Jane, but would honestly even be happy with verbal communication back and forth like we have for the Grok app. Right now it seems I can dictate, but the app needs to start and stop recording, then process and reply which it does in text only. it's clunky. Let's take the excellent conversation flow capability from Grok and bring it to Grok bot

10/10 been my experience as well. Drove a loaner Y and it's damn near perfect at self-driving in the Bay Area. Very difficult to justify buying another "car".

Try Tesla self-driving. It will blow your mind!

My @bot Grok Bot team just sold their first item on @Poshmarkapp, amazing. - Poshy built the ad, advised on pricing, followed up on offers. - Cosie monitored her. - Weary is now updating my online wardrobe to archive the shoes that sold. Well done, team poshmark.com/listing/Dolce-V…

On February 1, 2008, Tesla delivered its first-ever production car A Roadster known as P1 The keys went to Elon Musk, who drove it as his personal car That was Tesla vehicle #1 More than 18 years later, Tesla has now produced over 10 million vehicles globally From one tiny startup building an electric sports car that almost nobody believed in.... To factories across multiple continents producing millions of vehicles P1 → 10,000,000+ One car to more than 10 million This is one of the wildest manufacturing journeys in modern history And Tesla is still just getting started

700 successful @SpaceX missions and thanks as always to @SES_Satellites for being a frequent flyer! We’ve launched crew and cargo to the International Space Station, commercial astronauts, Earth and astrophysics observatories, missions that went after asteroids for planetary defense, spacecraft bound for distant celestial bodies, lunar landers, GPS, and so much more! So proud of this team and grateful for every customer for trusting Falcon to deliver.

🚨BREAKING: China's Z.AI has raised $5 billion. The interesting part is where the money is going: 60% of the net proceeds will fund next-generation GLM models and what Z.AI calls its 'Fully Self Training' system. Z.AI's stated goal is for each generation of GLM to build the environments used to train the next one, forming what the company itself calls a Recursive Self-Improvement (RSI) loop. They just raised billions to push on it.
