🇺🇸🇯🇵🇰🇷⚔️🇨🇳🇰🇵🧵 HOW THE UNITED STATES TURNED JAPAN AND SOUTH KOREA INTO IMPERIAL COLONIES AS PART OF ITS COLD WAR AGAINST CHINA AND THE DPRK American policy in the Asia-Pacific has always been centered in building up Japan’s industry and leveraging Tokyo’s power at the expense of the economic independence of other country’s in the region. This doctrine goes all the way back to the early 20th century as Theodore Roosevelt committed the United States to the establishment of a global empire and JP Morgan created a monopoly over large sectors of the American economy in the aftermath of the Panic of 1907. The Meiji Restoration, which established the Empire of Japan, brought industrialization and modernization to the Japanese economy. However, this was mostly done on the backs of foreign loans and had been a continuation of work already theorized in China under Sun Yat Sen, whose Three Principles (Nationalism, Democracy, People’s Livelihood) inspire Chinese socialism today and were based on the state-led economic frameworks of Alexander Hamilton and Abraham Lincoln. Sun himself was educated in Hawaii by protégés of Lincoln. And it ultimately led to this notion among leaders in Tokyo that Japan is now becoming a partner of the Anglo-American Empire. A major reason why this was is because Theodore Roosevelt agreed in the Taft-Katsura Agreement that the United States would give Japan control over the Korean Peninsula if they did not interfere with Washington’s violent seizure of the Philippines. However, what Tokyo didn’t notice at first is that they were not becoming a regional empire but a proxy of American imperialism. From there, the groundwork was set for Japan’s wars of mass genocide against the people of China, Korea, Russia and across the Asian continent. After its war with Russia in 1905, Tokyo fully annexed Korea in 1910, which would then be used as a launching pad for their wars against China. The Japanese previously launched a failed war against China in 1894, after which European colonial empires set up spheres of influence as part of the Century of Humiliation. And then in 1931 and 1937, as a result of false flag incidents staged by the Japanese Kwantung Army along the South Manchuria Railway in Mukden and the Marco Polo Bridge near Beijing, Japan launched the Asia-Pacific Theatre of World War II waging mass genocide and engaging in sexual exploitation against the people of China, Korea and across Asia. Unit 731 was established in Manchuria under the command of Dr. Shiro Ishii and with the approval of the puppet dictatorship in Japanese-occupied Manchuria led by former Emperor of the Qing Dynasty Puyi. 731 carried out some of the most cruel and tortuous human experimentations against civilian victims, including infecting prisoners with deadly diseases and amputating their limbs, conducting vivisection and organ harvesting, suffocating victims and hypobaric chambers and exposing prisoners to chemical, explosive and biological weapons. Even more outrageous is the fact that Ishii escaped prosecution after the US granted him immunity in exchange for research from Unit 731. And some of that research was used by the CIA for Project MKUltra.

NASA has just launched a new website for its Moon Base missions, which aims to build a permanent $20 billion U.S. base on the Moon. @SpaceX's Starship rocket will play a big role in these missions. "The Moon Base is a home away from Earth for Artemis astronauts who will live and work at humanity’s first lunar outpost. NASA is leading global teams of innovators across international space agencies, industry, and academia to build the Moon Base and establish an enduring human presence near the lunar South Pole for the benefit of all. Phase One (Now–2029): Experiment and Learn NASA will begin with a rapid series of robotic missions to scout the lunar South Pole region, test technologies, and prepare for surface operations ahead of future astronaut missions.: • A major increase in lunar activity, with up to 25 missions, including 21 landings. • Crewed and autonomous rovers for mobility demonstrations and surface preparation, along with four drones known as MoonFall and communications relay and observation satellites. • Early demonstrations of power, navigation, communications, and nuclear radioisotope heater unit technologies designed to endure the long lunar night. • Scientific payload opportunities integrated across landers and rovers. • The first tangible footprint of Moon Base effort, with four tons of payload delivered to test what works on the lunar surface. Phase Two (2029–2032): Early Habitation By 2029, NASA will transition to assembling semi-permanent infrastructure and initiating early habitation and logistics operations: • Deployment of expanded solar power systems and initial nuclear surface power capabilities, potentially including fission reactors and radioisotope power systems. • Upgraded rovers, potential advanced MoonFall drones, and early habitation elements. • Enhanced surface-to-orbit communications networks to provide reliable connectivity across the lunar South Pole region. • Delivery of up to 60 tons of cargo through as many as 24 landings using low-, medium-, and heavy-class cargo landers. Phase Three (2032 and Beyond): Sustained Human Presence This phase will scale operations to achieve a true enduring presence, with routine crew rotations and continuous surface activity. This is when living and working on the Moon becomes a reality: • Semi-permanent habitation modules with spacious interior for crew living and operations. • Operational fission surface power systems capable of delivering steady, reliable energy through the long lunar nights, leveraging in situ resource manufacturing. • Advanced logistics networks supported by crewed and autonomous rovers to keep the base supplied and functioning year-round. • Delivery of up to 38 tons of cargo annually to sustain habitats, power systems, logistics operations, and major science outposts, enabled by low-cost reusable heavy-lift capabilities."

I’ve left Google DeepMind. The last two years have been an incredible whirlwind. A couple years ago, I joined a small startup called Codeium. There, I got to ship Windsurf, train SWE-1 (a frontier agentic coding model), go to DeepMind in the $2.4B acquisition. Now, I decided to leave the acquisition money and DeepMind. I’m grateful to the mentors, teammates, and friends I worked with along the way. At Windsurf, thanks to @_mohansolo and Douglas Chen, I got to see what a fast moving startup that ships relentlessly and builds for the future looks like. I learned from @thenickmoy how excellent research leadership can drive outsized innovation. At DeepMind, I got to push the frontier of agentic coding, be part of the amazing team that shipped Antigravity and contributed to Gemini 3. DeepMind is a rare place: deeply curious people, exceptional research taste, and access to enormous compute and Google-scale infrastructure. A few things that I learned: 1. Finding the right hill to climb. Now more than ever, there are a multitude of directions to push the frontier in AI research. It’s easy to optimize for the wrong benchmark or capability. You should step back regularly to question if you are climbing the right hill, and adjust course often. 2. The secret to being a fast-moving team. Moving quickly is not just about working hard and long hours. It requires making concrete bets about where the world will be in 6 months, aligning around them, and cutting everything else. This was our journey from the Codeium Extension → Windsurf IDE → SWE-1 → Antigravity → Antigravity CLI 3. Silicon Valley is small. Since the split of Windsurf to DeepMind and Cognition, many of my colleagues have gone to other exciting places - Thinking Machines, OpenAI, xAI, Cursor, fast-moving startups, or started their own companies. I’m grateful to have worked with so many talented, hungry people whose stories are not yet finished. So what’s next? We are living in one of the most exciting and powerful times in human history. Just like we transformed software engineering, soon every industry, every unit of work will be radically transformed, democratized, accelerated. With this comes new challenges, and new doors of frontier research to be opened. More soon.

🦔Microsoft canceled its internal Claude Code licenses this week after token-based billing made the cost untenable, even for a company with effectively infinite cloud resources. Uber's CTO sent an internal memo warning the company burned through its entire 2026 AI budget in just four months. American AI software prices have jumped 20% to 37%, and GitHub (owned by Microsoft) is dropping flat-rate plans for usage-based billing across its products. My Take The AI subsidy era is ending in real time. The same company that put $13 billion into OpenAI and built the Azure infrastructure powering most of Anthropic's compute just looked at the bill from a competitor's coding tool and decided it was not worth paying. That is not a productivity failure on Anthropic's end. Token-based pricing is forcing every enterprise customer to confront the actual cost of running these models at scale, and the number turns out to be far higher than the flat-rate experiments suggested. This ties directly to my Gemini Flash post yesterday. Anthropic, OpenAI, and Google all raised effective prices in the last six months. Enterprises that built workflows assuming AI costs would keep falling are now watching annual budgets evaporate in months. Two outcomes look likely from here. Either enterprises scale back AI usage to fit budgets, which slows the revenue ramp the labs need to justify their valuations ahead of IPOs, or the labs cut prices and absorb the losses, which makes the unit economics worse at exactly the wrong moment. Both paths land in the same place, the numbers stop working, and somebody has to take the writedown. Hedgie🤗

Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946. For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids. An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better. This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

Crypto is not a safe haven for illicit finance. 📊 ~11% of illicit crypto volume was seized in 2025 – 55x the recovery rate for fiat. That figure comes from publicly reported actions by Tether, Interpol, the T3 Financial Crime Unit, and others — not a single agency estimate. 📌 For context: The UNODC estimates less than 1% of illicit fiat flows are seized globally each year. Even stripping out the Prince Group case alone (~US$15B in BTC), the remaining 2025 crypto seizures still run at roughly 10x that fiat baseline. 🔍 SlowMist and PeckShield tracked 8.3%–13.2% of stolen funds recovered or frozen in 2025 — reflecting fast incident response and tight coordination between exchanges, issuers, and law enforcement. The bottom line: Crypto crime isn't solved. But the idea that crypto is uniquely hospitable to illicit activity is increasingly a myth. Blockchain is transparent by design. Regulators and investigators are finally using that to full effect.

T3 Financial Crime Unit (T3 FCU), a joint crypto crime-fighting initiative launched by @trondao, @tether, and @trmlabs, has frozen over $450 million in illicit digital assets globally as part of expanding efforts to combat blockchain financial crime in coordination with regulators and law enforcement agencies. T3 FCU reported a nearly 44% increase in illicit proceeds intercepted during 2025 compared with the previous year, with enforcement agencies in the US, Spain, Germany, the Netherlands, and Bulgaria leading anti-money laundering and asset-freezing efforts.
