This is just one of many examples that make @isaiah_p_taylor so exceptional. I’ve earned a seat in truly elite circles across the military, software industry, broad USA government, and the venture world and I’ve seen the best. Isaiah is one of them and his ability to manifest this dream and build a company, that in turn built a modern nuclear reactor in record speed, is nothing short of the American dream…. He is proving to all of us how special our nation is and we really can do anything! Happy 4th!!

Thank you. There was real risk that it wouldn’t work live. There were concerns with how the chip would fare being run around with, risk of dropping, risk of boot up taking longer or headless mode failing, etc etc… When we actually did it, it took around 10s longer than we expected for the headless server to boot up; it came to like 3 seconds before I clicked the refresh button on stage 😂 control room was freaking out the whole time thinking something failed We will continue to operate live and transparently. At some point a live demo we do will fail, and that will be ok too. We decided at the very beginning that nuclear was going to have to be a transparent industry in order to make the worlds energy

On episode 74 of S3, we visit @valaratomics, the first startup in history to generate nuclear power, all while beating the July 4th deadline. In just 3 years, @isaiah_p_taylor went from pitching the idea on an Apple note to the reactor generating electricity, and now @nvidia is betting on that same reactor to power its next AI data center.

Atlas Shrugged made simple: 1. Society runs on a small number of highly capable producers – industrialists, inventors, engineers – whose work everyone depends on but takes for granted. 2. The system starts rewarding need over achievement: the more capable you are, the more you’re expected to sacrifice for those who aren’t. 3. Success gets treated like a debt – taxed, regulated, resented – until the most capable start asking why they bother trying at all. 4. One by one, led by a man named John Galt, they simply withdraw – walking away rather than keep propping up a system that punishes them for producing. 5. Without them, the whole structure collapses, revealing that the “automatic” prosperity everyone assumed was actually being generated by specific, irreplaceable people. 6. Atlas is the Titan from Greek myth, condemned to carry the sky on his shoulders forever – Rand’s stand-in for the producer class, holding up civilization while getting blamed for it. 7. “Shrugged” is the whole argument in one word: Atlas doesn’t fight, doesn’t protest – he just quietly sets the weight down. Nobody realized the sky was being held up by anyone in particular, until the day it isn’t. You don’t want us? We just go…🤷🏻‍♂️

The Road to Serfdom made simple: 1. Plan the whole economy: someone must decide what gets made and who gets what, since people don’t naturally agree on one set of priorities. 2. These decisions are too big and detailed for normal democratic debate, so power shifts to a smaller group who can just act – technocrats. 3. Fixed laws everyone can rely on get replaced by case-by-case rulings, because a plan needs flexibility, not predictability. 4. Dissent becomes a problem to manage, not an opinion to vote on – the plan can’t work if people are free to ignore it. 5. Enforcing all that selects for people most willing to be ruthless – Hayek’s “worst get on top” – i.e. negative moral selection. 6. Since economics touches everything (your job, home, speech), controlling the economy ends up controlling your whole life. That’s the "serfdom."

@PeterJ_Walker This makes sense — some investors will feel pot committed on a large seed. Would love to see the strength of the Series A - large/small, inside or outside lead. That would give more clarity on the types of Series A rounds versus just the probability of one happening.

I never thought I’d have a UFO sitting on my lawn. 😂 Shield AI has just unveiled their new AI-piloted fighter jet, the X-BAT. This Thursday, I’m joined by Shield AI’s Co-Founder and former Navy SEAL, Brandon Tseng, who breaks down the X-BAT in full detail. This autonomous fighter jet has a 2,000-mile range, is the world’s first AI-piloted fighter that doesn’t require a runway, and can take off and land vertically. This is one of those moments that makes me proud to be an American. Brandon also shares insight into other autonomous systems Shield AI has developed—systems already in operational use, including supporting the Coast Guard on counter-narcotics missions. @shieldaitech @brandontseng2

Earth is our runway. Introducing X-BAT, the world’s first AI-piloted VTOL fighter jet. With vertical takeoff and landing, long range, and full autonomy, X-BAT delivers combat power anywhere, anytime. This is the future of airpower. Watch the video: youtu.be/OnpuNlE3UxU Autonomy for the world. The greatest victory requires no war. #XBAT #Autonomy #NextGenTech #Airpower #Aircraft #Aviation #Defense
