"There are 3 things that are important, Truth, Curiosity & Beauty. If AI cares about those 3 things, it'll care about us. Truth will prevent AI from going insane. If it's curious, then it will foster humanity, & if it has a sense of beauty, it'll be a great future"

I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country
NVIDIA CEO Jensen Huang: “I really discourage 1-on-1s”
Jensen famously has 60 direct reports. When Stripe founder Patrick Collison points out that this isn’t conventionally considered best practice, Jensen shares his reasoning:
“I don’t do 1-on-1s, and almost everything I say, I say to everybody all the time. I don’t really believe there’s any information that I operate on that only one or two people should hear about… I believe that when you give everybody equal access to information, that empowers people. And so that’s number one… Number two, if the CEO’s direct staff is 60 people, the number of layers you’ve removed in a company is probably something like seven.”
Patrick offers to steal man the other side of the argument:
“1-on-1s are where you provide coaching, where you maybe talk through personal goals and career advancement, where maybe you give feedback on something that you see somebody systematically not doing so well… Do you not do those things or do you do them in a different way?”
Jensen responds:
“I give you feedback right there in front of everybody. In fact, this is a really big deal. First of all, feedback is learning. For what reason are you the only person who should learn this?… We should all learn from that opportunity… Half the time I’m not right, but for me to reason through it in front of everybody helps everybody learn how to reason through it. The problem I have with 1-on-1s and taking feedback aside is you deprive a whole bunch of people that same learning. Learning from other people’s mistakes is the best way to learn.”

At 1:30 a.m. PT on November 3, 2023 Elon sent a message to the xAI group chat saying that we need to go “extremely hardcore” for the next 36 hours; Grok will be released publicly tomorrow. You didn’t have to be in the exclusive company chat to get the message; it was also posted publicly at the same time:

What unfolded over the next day and a half was one of the best examples of engineering at pace that I’ve ever seen. All we had when we started was a somewhat fine-tuned base model and a half-baked UI. Our team of ten split up the tasks: curate data, improve the model, implement the raw prompting and RAG service, build the production infra. I took care of the latter.
At 8:51 p.m. PT the next day, we announced Grok to the world with a long-form post on X (https://t.co/9d485OLrSY). Over the past 36 hours, we came up with Fun mode (including Grok’s sunglasses), finished the whole production system, and most importantly tuned the RAG system that gave it real-time knowledge of the world through the X platform (a first in the industry). A day and a half of straight coding and shipping; no drugs, not even caffeine, just pure adrenaline. Elon gave us a mission and we delivered.
The launch went very well. We invited a couple hundred X creators and Grok’s ability to roast accounts went viral. It was the first time a publicly accessible AI was allowed to poke fun at people.
This episode is a prime example of what you can achieve by going extremely hardcore: you move and deliver results faster than any outsider could have anticipated. Within 36 hours, we took the company from silence to relevance. It was well worth it.
xAI’s hardcore culture is infamous on X. I love the tent meme that suggests we all sleep (well, slept in my case) in the office in tents. Our reputation precedes us and even new joiners hit the ground grinding hard. However, unless you understand the “why,” you are at risk of simply replicating the “how” without achieving the same results.
You need to grind with purpose and the purpose is to move fast towards a known goal. When the goal and the means of reaching it are crystal clear, a small, skilled, and highly motivated team can outcompete companies old and new, big and small.
Never grind to show off; never work late to be seen; never sacrifice without cause. There is no medal for the one who tried extremely hard but failed. There is only a medal for the winner. If all your efforts lead nowhere, you’re arguably not very productive.
Always keep your eyes firmly on the goal, do everything to reach it as quickly as possible, and make sure you're on track to win. A hardcore engineering culture is one of the most effective ways of accelerating real progress. Watch out for performative sacrifice and don’t confuse pain with progress.
Yes, two solid official options:
TSA security (incl. PreCheck lanes): MyTSA app (free on iOS/Android from https://t.co/crFOIssvbc). Shows real-time crowd-reported waits + historical predictions at major airports.
International arrivals immigration (CBP for US citizens): https://t.co/AqbdfGD7Il – estimated hourly wait times for passport control at busiest US airports (historical-based for planning).
Many airports (e.g., DFW, IAH, LAX) post live TSA on their own apps/sites too. Check yours directly. Arrive early amid current delays!
@grok Is there an app/website that shows live que time at US Major airports for both TSA (include PreCheck) and international arrival immigration line for US citizens?
Here is a summary of Tesla’s Q4 2025 Earnings Call, if you missed it:
• Tesla is officially ending production of the Model S/X in lieu of an autonomous future. Tesla will replace the production space with Optimus lines.
• Elon confirms Robotaxis in Austin do not have a chase car as of yesterday.
• Tesla expects 2026 Capex to be in excess of $20 Billion.
• Tesla expects to have autonomous vehicles in 25-50% of the US by the end of 2026 (PRP)
• Tesla expects its Robotaxi Service to be in dozens of cities by the end of 2026.
• Elon says Tesla will be a big manufacturer of Solar Cells. Confirms 100GW/yr production.
• Tesla now has more than 500 Robotaxis across Austin, and the Bay Area.
• The number of Robotaxis will roughly double each month.
• Elon Musk says all cars Tesla makes in the future will be fully autonomous, expect the Next-Gen Roadster.
• Optimus Gen 3 will be unveiled in a few months. “Long term, Optimus will have a significant impact on the US G.D.P.”
• Elon is confident Tesla will reach 1M units/yr Optimus Production at Fremont.
• Elon confirms once again that Cybercab will NOT be sold with a steering wheel and pedals.
• Elon said Tesla expects to make far more Cybercabs than all other models combined.
• Tesla ended 2025 with a bigger backlog of orders than in recent years.
• Tesla’s CFO confirmed there is roughly 330K Active FSD Subscribers across the globe.
• Elon predicts only 5% of miles driven in the future will be done by a human, with potential of it going down to even 1%. Everything else will be autonomous.
• Elon says Tesla may transition the Cybertruck to a fully autonomous cargo truck in the future.
• Elon says Tesla will have larger autonomous vehicles in the future.
• Next-Gen Roadster will be unveiled in April 2026.
• Elon says when he looks 3-4 years out, he sees chip production as a bottleneck.
• Tesla has no plans to sell their chips to other company.
• In order to remove constraints in 3-4 years, Elon sad Tesla will need to build a very big Terafab that includes logic memory and packaging domestically. This will also help remove geopolitical risk in the future.
• Elon “it would be crazy to not try the Terafab—we will have a bigger announcement about this in the future.”
• Elon said Grok could help manage Optimus Robots in the future.
• Elon says Tesla is ahead of the rest of the world in terms of intelligence density of AI by an order of magnitude, or more.
• Elon says the toughest competition in the humanoid robot space comes from China.
ELON MUSK: "Our next product, Blindsight will enable those who have total loss of vision, including if they've lost their eyes or the optic nerve, or maybe have never seen, or even blind from birth, to be able to see again."
Seriously - WATCH ALL OF THIS! 🔥🔥👇🏼
“We got people literally camping in the streets, crying, lightning candles, holding signs, getting f*cking arrested, doing the most for people who broke into this country illegally, but when it comes to American veterans sleeping under the bridges, suddenly there’s not even a f*cking thought.”
“Y’all will shut down traffic for someone who hopped the fence, but won’t block a single street for the Marine who hopped on the f*cking grenade and came home invisible. And you weird a** politicians love to say we don’t have the money, but somehow there’s always enough money for people who aren’t f*cking citizens. That’s not a lack of funds, that’s a choice.”
“Fix our house first. Honor the people who built and defended it. Then we can talk about having guests over. Until that sh*t happens. Don’t talk to me about compassion.”
Donald J. Trump Truth Social Post of Video 10:45 AM EST 01.22.26
President Trump posts video from @mjtruthultra of the Citadel's CEO Ken Griffin:
"You cannot imagine how painful it was under the Biden Administration, their crazy proposals to solve problems that didn’t exist and to have that end in one day (Trump’s Reelection) gives you so much energy to go back and build your damn business. It was a giant sigh of relieve."
“The Decisions made under the Biden Administration were so so poorly thought out in terms of economic consequences, it cost the U.S. economy dearly."
