True story: Harvard Business School rejected me in '91. When I got the news, I checked to see if they'd cashed my $100 application fee check. They hadn't, so I did a "stop payment". When they called, trying to collect, I suggested they could learn a business lesson from this. 😂

Polymaths in this era will be undefeated

@garrytan I heard you say at the retreat, long before Claude Code, that AI will bring back the Da Vinci polymath era. Not many sentences have aged this well.

Ukraine crushed NATO partners during naval exercises near the coast of Portugal. Ukrainian Magura V7 naval drones simulated the sinking of a frigate during the drills. After several simulated hits, NATO sailors even wrote in the chat: “So are you going to attack us or not?” — not realizing they had already been attacked. Ukrainian operators commanded the “red team” and won all five combat scenarios. The exercises highlighted something important: unmanned naval systems, combined with Ukraine’s real combat experience and operational planning, can pose a serious challenge to traditional naval forces. They also demonstrated that many militaries — including NATO — are still not prepared for this new type of warfare. I have said this before: today it is not Ukraine that needs NATO, but NATO that needs Ukraine. Source: FAZ

This robotic hand can weave itself together in minutes. Allonic developed a process that "braids" robot bodies around a 3D-printed skeleton in a single automated step. The tech draws from the textile industry, using braided fibers instead of traditional mechanical joints and bearings. Their braiding system grows tendon-driven structures directly onto skeletal cores, creating flexible yet durable parts without screws or assembly. One finger only needs 4 skeletal elements. Then thousands of braided fibers wrap around them to handle force and articulation. The software converts designs directly into machine code that runs the braiding process. But what matters is that robotic hands like this can cost up to $30,000, ~20-30% of a humanoid robot's total price. Allonic's braiding process could crush those costs while enabling custom designs at scale.

@FutureJurvetson Wow. I had no idea. I thought rockets were developed by the Germans in WWII. Thanks for sharing!

🚀 Today is the 100-year anniversary of the first liquid-fueled rocket launch. Like the Wright Brothers, Robert Goddard’s flight changed rocketry forever, pioneering today's mainstay, liquid-fueled SpaceX rockets. Here are my artifacts from his 1926 flight (last photo). But first, I am pointing to a museum replica of Nell — Goddard’s 10’ tall rocket powered by gasoline and liquid oxygen. It went just 41’ up in 2.5 seconds, hitting 60 MPH, but it marked the dawn of the space age. The New York Times publicly mocked his work in 1920, but Goddard persisted. Fearing further criticism, Goddard kept his 1926 launch secret for nearly a decade. Go Goddard, go, go go! “There can be no thought of finishing, for aiming at the stars, both literally and figuratively, is the work of generations, but no matter how much progress one makes there is always the thrill of just beginning.” — Robert Goddard From the Future Ventures’ space museum, last photo: 1) Inner nozzle from the first flight Starting on the far right, the alundum cement rocket nozzle liner from the liquid-fueled rocket launched by Robert H. Goddard, likely the world's first on March 16, 1926. The piece measures approximately 1.25 x 2.25 x .5 inches and has scorch marks on the interior from use. This artifact was given to Frederick C. Durant III by Goddard’s widow, Esther Goddard, and has been kept in an envelope labeled in Durant’s hand, “Ceramic rocket nozzle liner used by R. H. Goddard in 1920s, possibly from the 1926 (March 16) flight.”   Frederick C. Durant III, the former head of astronautics at the Smithsonian’s National Air and Space Museum, was one of the world’s foremost authorities of spaceflight and rocketry. This is one of several artifacts he received from Esther Goddard, one of the four people on the crew for the launch of March 16, 1926, and from her testimony, he determined the 1926 flight as the likely origin. The small size of the piece lends credence to this conclusion, as Goddard’s rocket experiments grew larger and larger over time. 2) Fuel valve remains from a failed experiment Bottom left. Fuel-feed-rate needle valve from one of Goddard’s early rockets, circa late 1920s/early 1930s. The piece measures approximately 7 x 5 x 2” and consists of a valve passing through a longer pipe segment attached to a fragment of a larger base; a short bracket extends from the base, which was damaged in a blast during rocket experiments. The needle valves were located near the top of Goddard’s rockets and were a critical element in controlling his fuel feed line and tank systems. This artifact was given to Frederick C. Durant III by Goddard’s widow, Esther Goddard. 3) Fuel Tank Baffle Upper left. Bi-level metal rocket fuel tank baffle from one of Goddard’s early rockets, circa mid-to-late 1920s. The piece measures approximately 3.5″ in diameter and 2.25″ tall and consists of two discs connected by four rods. This artifact was also given to Frederick C. Durant III by Goddard’s widow, Esther Goddard. The baffle was an important element of Goddard’s fuel tank design, used to combat the ‘slosh’ of liquid propellant during flight. A couple more Goddard quotes that remind me of @ElonMusk: “Every vision is a joke until the first man accomplishes it; once realized, it becomes commonplace.” "It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow."

Liquid-fueled rockets had their 100th birthday today. Crazy that the technology has been used to give us so many modern comforts, while also unlocking the stars. Imagine where we will be in 100 years from now.

I am leaving the Washington Post to join a new journalistic venture backed by Politico founder Robert Allbritton that will be both the hometown publication the D.C. region sorely needs and a scrappy and fearless national news organization. I hope you'll join us.

Thomas Massie just went nuclear on Trump’s DOJ for bringing zero “charges, arrests, or investigations” over the Epstein files. “Who should be investigated?” “I’ll name them right here.” “Leon Black.” “Jes Staley, accused of terrible things.” “Leslie Wexner.” “Why did the FBI list him as a co-conspirator in their own documents in a child sex trafficking case, and then tell him that they had no questions for him?” “Over 3 million documents describing horrible things, unspeakable things, much of it redacted.” “Over two dozen people have resigned, CEOs, members of government worldwide.” “But I haven’t seen any arrests or investigations here in the United States.” “Prince Andrew, Duke of York, who has since been stripped of his royal titles due to his affiliation with Jeffrey Epstein, has been arrested.” “Peter Mandelson, who previously served as UK’s ambassador to the United States, resigned in disgrace from UK’s House of Lords and the Labour Party, and he’s been arrested.” “Former Prime Minister of Norway, Thorbjørn Jagland, has been charged.” “But we don’t see any charges, arrests, or investigations in the United States.” “What do we see?” “We see our FBI director celebrating in the locker room at the Olympics overseas.” “We need justice.”

Great discussion. I can correct a few of the early memories for history. The chip behind SGI was the "Geometry Engine". It was not Jim Clarke's thesis project. He was a prof. at Stanford, and the Geometry Engine was a project of him and his extraordinary grad students. No computer company wanted to add a real-time 3D chip, so Jim founded his own company, Silicon Graphics. If you want to read more of the history of 1994/1995, SGI and Netscape, enjoy: therealmccrea.com/2014/01/09/jan…
