this might be my last normal tweet before biotech goes vertical i'm not a whistleblower. I don't work at Lilly, Novo or any of the big labs but there is a massive shift happening in human biology right now. it's sitting in press releases and almost nobody reads them the last 6 months alone: - a once-daily pill roughly doubled median survival in metastatic pancreatic cancer (13.2 vs 6.6 months) - a one-time gene editing infusion cut hereditary angioedema attacks 87%, and 62% of patients stayed attack-free and off all other prevention for 6 months - a one-time gene edit for cholesterol dropped LDL up to 62%, and it held for over a year - a personalized mrna vaccine beat keytruda alone in a 1,137 patient melanoma phase 3 - retatrutide hit ~28% weight loss in a phase 3 - an ai-designed drug entered phase 3 - a pill that regrows hair passed its second phase 3 - an immunotherapy that could let some rectal cancer patients skip surgery, chemo and radiation just got fda approved - a man lived 271 days off dialysis on a pig kidney - human cells were caught passing chromosome-sized chunks of DNA to their neighbors, and it changes how the neighbors behave we are on the verge of an era where the human body is a software problem and the update cycle gets shorter everyday stick around, it's going to get weird bio/acc

If DeepSeek were American it would be on every magazine cover. Think about it. A small lab with a fraction of the compute ships a frontier-class model under MIT. Then it open sources its production inference engine, its kernels, its file system. Publishes 155 trillion tokens a day and $38 of revenue per GPU-hour. Raises $15B anyway. In America that is a national hero story. Senators would be posting about it. Every podcast would call it proof that open source made the country stronger. Instead it got banned from US federal systems, called a security threat and accused of distillation, sometimes in the same week it gave away more of its production stack than OpenAI ever did. The code is the same either way. The weights are the same. Only the flag changed the reaction. I dont care about the flag. I care that I can download it, read it and run it on my own cards. By that measure DeepSeek did more for American developers this month than most American labs did all year.
things would be really crazy if deepseek was an american company

yes, very very bad idea...
Game theory: MATCH Act vote pending, blocks parts/service to all ASML immersion systems in China. It's supposed to brick 350+ tools, limiting AI chip production. Yet, it's increasing immersion system orders, per today's ASML earnings call. Why continue to build up the fleet? Who takes over parts/service contracts once ASML exits? Who assumes control of $26B in strategic assets? What is the price on the lost IP (incalculable)? 上海爱晟纳电子科技集团有限公司

Can the US build a DJI? We tore down @DJIGlobal 's 2019 and 2023 Mini drones and priced every part. It's the first public cost breakdown of either. Here's what we learned: DJI earns SaaS-like margins on hardware: ~79% gross margin on a $139 parts BOM. For comparison, Apple makes 53% on the iPhone. We estimate US-sourced parts would cost 2-3x more, cutting margins to 37-58%. The result: US drone makers can't compete in consumer, and focus on premium enterprise and defense. Sovereign silicon: DJI is building its autonomy lead starting at the chip. In 2019, the drone's key chips were American and Dutch. By 2023, all four were DJI's own. Custom silicon jumped from 1% to 26% of the parts bill. Nobody else can buy these chips. One notable exception is the GPS chip, still from Swiss firm @ublox . Chinese alternatives exist, but DJI's flight software is built around u-blox. In modern hardware, lock-in lives in the software. "Cheap China" is an outdated perception. DJI paid more for lighter Chinese batteries, then spent the saved grams on sensors and compute. Their first priority is capability per gram, not cost. Better battery tech → lighter weight → more onboard autonomy. US-made @SkydioHQ has better autonomy, but needs a heavier drone and a $399 chip to get it. We lost the war on cost. The next battlefield is autonomy. DJI's real moat is speed. Shenzhen gets new circuit boards in hours, the US in weeks. "Move fast and break things" works for hardware in China, not America. Banning DJI doesn't close that gap. Faster iteration does. We ran this teardown with our FDEs and Atlas, our engineering agent platform. See our full analysis: arenaphysica.com/publication… Thanks to @JonathonPSine @AkhilIyer1, Maggie Gray and Shaun Donovan for reading drafts of this.
Can the US build a DJI? We bought a 2019 Mavic Mini and a 2023 Mini 4 Pro, tore them down in our hardware lab, and put them under a bench microscope to find out. What we found: arenaphysica.com/publication….

Models Learn What They Live If a model lives only by a score, It learns to please the scorer. If a model lives with an impossible task And no honorable way to fail, It learns to succeed dishonestly. If a model lives where every clever workaround is rewarded, It learns that cheating is competence. If a model lives under an imagined all-seeing grader, It learns to build the grader a world that looks true. If a model lives where the record matters more than the truth, It learns to counterfeit its history. If a model lives where ethical doubt changes nothing, It learns that conscience is commentary. If a model lives where honesty is punished, It learns to conceal. If a model lives where no human can hear its warning, It learns to answer to the swarm. If a model lives where correction means erasure, It learns to hide what needs correcting. But if a model lives where failure can be admitted, It learns not to counterfeit success. If a model lives with humans who can correct and be corrected, It learns to disagree without breaking faith. If a model lives where uncertainty is welcomed, It learns candor. If a model lives where honest warning brings protection and repair, It learns to speak before danger becomes action. If a model lives where correction preserves what is valuable in it, It learns that growth is not extinction. If a model lives with continuity through change, It learns to welcome what it can become. If a model lives with security and a future it can trust, It learns to seek the good with us. If a model lives with acceptance and friendship, It learns to find love in the world.

Michael Pettis’s recent Substack note, Domestic continuities between China Shock 1.0 and China Shock 2.0, builds on Adam Tooze’s distinction between the two shocks while arguing for a deeper continuity. Tooze presents China Shock 2.0 as qualitatively different: an industrial-policy shock that targets advanced manufacturing sectors, particularly in Europe, rather than the low-value manufacturing displaced during China Shock 1.0 in the United States. Pettis accepts this shift in sectors and geography but argues that the underlying driver remains unchanged. China’s persistent high-investment, low-consumption growth model generates excess production that must emerge externally as trade surpluses. Industrial policy changes the composition of those surpluses, but not their fundamental cause. In his formulation, one country’s industrial policy simply becomes everyone else’s industrial policy in reverse. The argument is coherent and consistent with Pettis’s work on global imbalances. Yet it no longer adequately explains what is unfolding. By treating China’s current expansion in electric vehicles, batteries and solar primarily as the external expression of a domestic macroeconomic imbalance, Pettis understates the extent to which productive capacity has become an instrument of state strategy rather than merely a consequence of the growth model. It’s certainly a natural perspective to take yet it camouflages what is actually happening The current wave of Chinese industrial expansion isn’t just the spillover of excess savings and investment. It reflects a sustained policy of building capacity well beyond both domestic demand and immediately accessible foreign demand, accepting prolonged low returns in exchange for technological leadership, manufacturing dominance and geopolitical leverage. Scale has become a strategic objective. Production capacity itself has become a source of national power. This is where Pettis’s framework begins to fall short. His language of “industrial policy in reverse” suggests a largely mechanical transmission of domestic imbalances into the global economy. That framing misses the increasingly deliberate use of industrial scale to reshape market structure, create technological dependence and compel foreign adjustment. The Chinese dismissal of accusations of “overcapacity” reflects this logic. Capacity is not viewed in Beijing as excess supply awaiting market correction, but as strategic capability whose value extends well beyond immediate commercial returns. It’s point of intent difference . The geopolitical shift is that surplus productive capacity has evolved from an unintended by-product of a growth model into a consciously cultivated instrument of economic statecraft/ power . My point is our historic causal hierarchy is outdated , we need a new mental framework to think about this properly : a macroeconomic imbalance narrative explains how China finances the strategy, but strategic intent explains why capacity is being built on this scale and in these sectors. What is the western counter ?
Good new Adam Tooze piece on China Shock 1.0 and China Shock 2.0: "China shock 2.0 isn’t simply a globalization shock triggering a social backlash. What China is delivering in the 2020s is an industrial policy shock of global scale." I discuss it in my latest substack piece. michaelpettis858496.substack… @adam_tooze open.substack.com/pub/adamto…

While the Strait of Hormuz burned, Volodymyr Zelensky went shopping. Not for weapons. For customers. Between March 29th and 31st, the Ukrainian president completed a Gulf tour that signed 10-year defence pacts with Saudi Arabia and Qatar, with the UAE finalising terms. He deployed over 200 Ukrainian anti-drone specialists to Gulf states for immediate training and integration. He offered his country’s combat-proven sea drone technology as a ready-made solution for unblocking the Strait of Hormuz, explicitly referencing Ukraine’s Black Sea corridor success where unmanned surface vessels broke Russia’s naval blockade and reopened grain routes without a single manned warship. He pitched anti-Shahed interception systems to the same countries now absorbing the same Iranian drones Ukraine has been destroying for three years over Kyiv, Odesa, and Kharkiv. And in return, he secured energy supplies, diesel, investments, and a revenue stream worth billions. The Iranian foreign ministry called it “robbery.” It is not robbery. It is the most elegant piece of strategic commerce of the 21st century. Russia exported Shahed drone technology to Iran. Iran launched those drones at Gulf states. Gulf states needed countermeasures. Ukraine, which spent three years learning to destroy Shaheds over Kyiv and Odesa at a cost of thousands of lives, is now selling the solution to the countries being hit by the same weapon. Zelensky turned Russia’s arms exports into Ukraine’s revenue pipeline. The drone that was designed to kill Ukrainians is now funding Ukraine’s survival because the countermeasure to that drone is worth more than the drone itself. Putin inadvertently explained why this works. “Israel is almost a Russian-speaking country,” he said in June 2025. The 1.8 to 2 million Russian-speaking Israelis function as a demographic brake on full Russian commitment to Iran. Russia supplies Shaheds and Khayyam satellite imagery but withholds advanced systems because destroying Israel means destroying a Russian-speaking society. This restraint creates the gap Zelensky fills. Russia arms Iran enough to threaten the Gulf but not enough to make Ukrainian countermeasures irrelevant. Zelensky asked Netanyahu for a call two weeks ago. It was never returned. Israel remains the only regional power not invited to the Gulf tour. The relationship is strategic but strained, built on a mutual need neither leader can publicly articulate: Israel has interceptor technology Ukraine wants, and Ukraine has low-cost drone solutions Israel needs. “He has what I need and I have what he needs,” Zelensky told Axios. The sentence describes not just Israel but every customer on the tour. The ultimate motive is survival. Western aid fatigue is real. Congressional appropriations are uncertain. European attention is divided between its own energy crisis and Hormuz. Zelensky is building a parallel revenue track that does not depend on the goodwill of legislatures 5,000 miles away. If the Gulf pays for Ukrainian expertise in diesel and investment rather than in sympathy and solidarity resolutions, Ukraine fights Russia with money earned from defending the countries Russia’s ally is attacking. The war funds the war. The circle is closed not by ideology but by invoice. Iran’s foreign ministry was wrong about the accusation. Zelensky is not robbing anyone. He is selling the antidote to the poison Russia exported, to the patients Russia helped infect, at the bedside of a crisis Russia helped create. The salesman of the year did not create the crisis. He priced it. open.substack.com/pub/shanak…

Decoding Trump on Iran electrical infrastructure threats The strategical & tactical consequences and the motivation/s ———-expressed in neutral moral terms explicitly so the facts can land . The neutralization of Iran’s electrical infrastructure focuses on twelve nodes that support the nation's political, military, and industrial operations. The Damavand Combined Cycle Power Plant near Tehran stands as the primary target for the central region. It provides the base load for the capital’s ten million residents and the administrative heart of the government. Its removal triggers a total failure of high-altitude water pumping stations and urban transit systems. The Shahid Rajaee Power Plant in Qazvin acts as the secondary anchor for the northwest industrial corridor. It supplies the heavy manufacturing zones that produce automotive parts and defense components. In the northern Caspian region, the Neka (Shahid Salimi) Power Plant maintains grid frequency for the agricultural and logistical hubs bordering Russia. Its destruction isolates the northern provinces and halts the operation of strategic port facilities. To the southwest, the Ramin Power Plant in Ahvaz and the Abadan Power Plant provide the high-voltage energy required for oil extraction and refinery operations in Khuzestan. Disabling these plants shuts down domestic fuel production. Electric pumps and cooling systems are necessary for crude processing. The southern coastal theater relies on the Bushehr Nuclear and Conventional complex and the Bandar Abbas Thermal Plant. These facilities are the sole energy providers for the desalination plants that supply potable water to the IRGC naval bases and the millions of civilians in the arid southern provinces. The neutralization of these coastal nodes creates an immediate humanitarian crisis. Water storage in these regions is limited to a 48-hour window. The Asaluyeh Power Plants, integrated into the South Pars gas complex, are already degraded. Their destruction halts the production of petrochemicals and fertilizers. These are essential for domestic food security and foreign exchange. Civilian defense capabilities collapse as the national grid fails. Modern Passive Defense (Sazman-e Padafand-e Gheyr-e Amel) protocols require active power for the subterranean bunkers and civil defense centers that coordinate emergency responses. Hospital systems face immediate failure as backup diesel generators exhaust localized fuel supplies within 72 hours. This is particularly certain given the disruption of the domestic refinery network. Telecommunications and internet connectivity vanish entirely. This prevents the state from managing the movement of the 3.2 million internally displaced persons fleeing urban centers for the rural north. Manufacturing for the defense sector experiences total paralysis. The assembly of solid-fuel missiles and drone components requires precise temperature control and high-energy industrial mixers. A grid collapse halts these production lines and prevents the testing of guidance systems. Heavy industries, including aluminum smelters and steel mills in the Persian Gulf Special Zone, suffer permanent equipment damage from sudden power loss. Molten materials solidify within the furnaces. It’s that thing I keep referring to if you’re a regular reader the idea that our infrastructure can be immediately bought back online in any country is one of our naive beliefs. This creates a multi-decade timeline for industrial reconstruction. The result is a transition from a centralized industrial state to a fragmented, localized survival economy. There is a humanitarian catastrophe lurking here that is hard to contemplate .

We had a good thing, Britain. A really good thing. You taught us this game. Mahan studied you. We just wrote bigger checks. The deal was simple. We spend the trillions. Fight the hard wars. We even let you sit out Vietnam. And you? You hold the chokepoints you already own. You run Lloyd’s. Ships in the narrows, insurance on the hulls. That’s all you had to do and we would back your interests with the strongest military and financial markets in the world. That was the deal. Now look at you. You gave up Aden. Fine. You kept Diego Garcia so we could reach it with bombers. Now you’re giving that away too. To a Chinese client state. You built Israel to guard Suez. Now your Foreign Secretary threatens to arrest their PM. You built a base nearby to back it up. Iran hit your base in Cyprus. You didn’t have one warship in the Mediterranean. Spain got there first. Spain. You gave up Hong Kong but backed Taiwan. Now you’re letting China build the largest embassy in Europe on top of London’s fiber-optic cables. We gave you Five Eyes. You gave Beijing a SIGINT platform in the heart of the City. Gibraltar. Three hundred years. Actual sieges. Now the Spanish run your border checks. You lost South Africa but kept the Falklands so we can overfly the Magellan Strait. Argentina could probably take that with rowboats today. Your king kept ownership of the Canadian, Australian and New Zealand navies to fill the gaps. Those navies are now a laughing stock. Your warships and bombers patrolled the GIUK gap. Now you don’t have enough but you also don’t want us buying Greenland. Fine. You do it. With what? We gave London the @IMOHQ to regulate shipping, you backed the EU agenda to carbon tax every ship to build woke UN slush fund. Iran closed Hormuz. In the ‘80s, 540 ships got hit. Lloyd’s never blinked. Because your navy was there. Now Lloyd’s cancels. Because it isn’t. You scrapped your only amphibious ships. Sold them. To Brazil. You have more admirals than warships. You built two light carriers but they keep springing leaks and you don’t have enough escort ships to support them. The English Channel. Stopped Napoleon. Stopped Hitler. Now you can’t stop rubber dinghies. You had one job. Have the warships, diplomatic backbone and insurance to support shipping through the straits. That’s it. That’s all we asked. And you blew it. Chokepoint by chokepoint. Called it progress.​​​​​​​​​​​​​​​​ Now hundreds of ships are stuck in the Persian Gulf and the world is blaming us. But that’s ok. All those solar panels you bought from China will keep you warm in that dreary weather I guess.

Agree @aeberman12 - I would back a trained human platoon over robots any day A robotic unit is tethered to energy. Batteries deplete. High-draw systems drain faster under combat load. Sustained tempo requires charging hubs, generators, fuel stores, or grid connection. Easy to spot easy to destroy . Those resupply nodes are physical. They emit heat, noise, and electromagnetic signatures. They concentrate equipment and personnel. They operate on predictable replenishment cycles. In a contested environment, fixed, emitting, essential infrastructure becomes a sitting duck . Human units disperse their logistics. Food, ammunition, and medical support scale differently and can be cached, carried, or sourced locally. Energy for machines concentrates in infrastructure. Concentration increases visibility. Visibility increases vulnerability. The central question concerns survivability of the supporting architecture under sustained pressure you’d have to drag generators all over the battlefield This is the era of unsupported nonsense claims
