Often said about me: "From Infinity" & "Too Beyond"




JUST IN: On March 14th, a Chinese engineer posted a tutorial explaining how to use passive infrared sensors to detect and track American fighter aircraft without triggering their radar warning receivers. Three weeks later, an American F-15E Strike Eagle is in a crater in central Iran. The IRGC says it was brought down by a “new aerospace defense system.” The system appears to be exactly what the tutorial described. The principle is elegant. Radar is active: it emits radio waves that bounce off the target. Every American fighter carries a warning receiver that detects those emissions. But infrared detection is passive. It reads heat. Jet engines produce heat. A passive sensor tracking that signature emits nothing. The warning receiver stays silent. The pilot does not know he is being tracked until the missile is already in the air. The F-15E is not stealth. But the tutorial was designed for the F-35. The same principle applies: stop looking with radio waves, start looking with heat, and the $1.7 trillion stealth programme becomes a coating on an airframe that is still hot. The tutorial was posted on Chinese social media, translated within days. Three weeks later, the technique appears to have been operationalised. This is the second time passive tactics have brought down a generation-defining American combat aircraft. The first was March 1999, when a Serbian battery commanded by Colonel Zoltan Dani shot down an F-117 Nighthawk over Kosovo using long-wavelength radar and visual cueing. The F-117 was retired within a decade. The lesson: stealth is optimised against specific frequencies. Change the sensor, change the war. Iran’s layered defense integrates Russian S-300 for radar search, Chinese electro-optical trackers for passive acquisition, and Iranian Raad-family missiles with onboard IR cameras for terminal guidance. Radar finds the area. Passive sensors track without emitting. The missile guides on heat. The pilot’s systems detect radar. They do not detect infrared. That gap killed the F-15E. Now consider who built this kill chain. Russia supplied the S-300 base. China supplied the passive sensors. Iran assembled the hybrid. And China is simultaneously the country supplying the rare earth magnets in every F-35 engine, the country blocking the UN Security Council resolution to reopen the Strait of Hormuz, the country paying yuan tolls to transit the closed strait, the country co-authoring the five-point peace plan with Pakistan, and the country whose engineer posted the tutorial that appears to have taught Iran how to shoot down the aircraft China helps manufacture. China occupies every chair at this table. Supplier of the components that build the jet. Teacher of the countermeasure that kills it. Mediator of the peace. Blocker of the UN resolution. Beneficiary of the closure. The molecule passes through the strait in Chinese tankers paying Chinese currency while the aircraft designed to reopen it falls using Chinese technology. The F-15E did not fail. The assumption that the enemy would always look with radar failed. And the country that taught the enemy to look with heat is the same country offering to negotiate the peace while its rare earth controls ensure the replacement cannot be built without buying from the nation that taught the enemy to destroy the original. The kill chain starts in Beijing. The peace talks start in Beijing. Both end in the same crater. open.substack.com/pub/shanakaans…

Clavicular left the interviewer completely speechless after explaining just how far he takes heightmaxxing 😭 “If they make you take your shoes off, you can sag your pants to hide your heels… and just tiptoe maxx.”


Why does Canada have the longest MRI wait times in the developed world? The Ontario health ministry has a central licensing department for all imaging. In 2024 less than 30 licenses were given out. I know imaging centres that have machines collecting dust for years waiting to be licensed. This is a classic Soviet style artificial supply constraint created by bureaucracy. Meanwhile Canadians are driving to Buffalo or overseas for private MRIs.








Thrilled to share my first pre-print, where we show that episodic memory formation is theta-rythmic! Thanks to my supervisor, Katherine Duncan, and collaborators for your support and insights. Looking forward to where this research program takes us! osf.io/preprints/psya…


I spent time in Shenzhen last year and when I saw Merz come back from China saying Germans need to work more I immediately knew what broke his brain because I lived the exact same cognitive shock my first week in Huaqiangbei I burned through 4 prototype iterations of a motor controller board for less than a thousand bucks total, back home a friend was working on something similar and spent over 12 thousand for a single revision that took almost two months to arrive when you live that contrast in your own hands with your own project something permanently shifts in how you see the world and it goes way deeper than speed & cost what Shenzhen actually built is a collective learning organism, imagine 20 PCB fabs 15 injection mold shops 30 component distributors and a hundred firmware freelancers all within a 2km radius, looks insanely redundant from the outside until you realize redundancy is actually information density in disguise I watched this firsthand with an injection mold supplier I was working with, this guy had seen a hundred founders iterate similar thermal designs over 6 months so he proactively modified his tooling before I even opened my mouth, he knew what I needed before I knew what I needed, the intelligence lives in the relationships between the nodes and it compounds daily the west thinks about manufacturing as a cost center you optimize by centralizing… China accidentally built a distributed neural network of manufacturing intelligence where knowledge diffuses horizontally across thousands of agents faster than any single western company can process internally so when Merz comes back and says we need to work a bit more I think he saw the problem but COMPLETELY misdiagnosed the solution, telling Germans to work harder is like telling a horse to gallop faster when the other side built a combustion engine the gap is ARCHITECTURAL it’s ecosystem density, you need a custom connector in Shenzhen you walk 200 meters, in Munich you send an email and wait 3 weeks it’s iteration speed, parallel search vs sequential optimization at the system level, it’s risk tolerance, Chinese founders ship something broken on Monday fix it Tuesday ship again Wednesday while European companies are still in the approval phase for the pilot program of the feasibility study… and Merz only saw the surface, what he missed is the tier 2 cities like Hefei Chengdu Wuhan replicating the Shenzhen model at scale right now BYD going from irrelevant to outselling every european automaker combined in roughly 5 years, Huawei building its own 7nm chip under maximum sanctions when every analyst said it was physically impossible & behind all of that a government that treats advanced manufacturing as an existential national priority while europe debates whether AI needs another ethics committee I think what we’re watching is the most asymmetric economic competition in modern history and most western leaders are still framing it as a productivity problem when it’s actually an ontological one Europe & America are optimizing variables that China stopped tracking years ago meanwhile China is compounding on dimensions the west has no framework to even measure Merz at least had the courage to name it out loud and I respect that genuinely but working a bit more inside a broken architecture just means you arrive at the wrong destination slightly faster
