Frankly, Huawei’s announcement yesterday in Shanghai has just put in black and white what I’ve been trying to make you understand here for years.

To break it down simply, Huawei just announced at the IEEE ISCAS symposium a new physical law that replaces Moore’s Law—they call it the tau scaling law, and it literally changes the global semiconductor paradigm. In essence, instead of continuing to shrink transistors, which is hitting insurmountable quantum physical limits, they’re now optimizing the tau time constant across 4 levels simultaneously and achieving performance gains equivalent to what the Americans get with their EUV lithography at $200 million per machine—except they haven’t had access to that lithography since the 2019 sanctions.

China is therefore surpassing Silicon Valley on its own turf and making it obsolete, and what’s really playing out is the exact opposite of what Washington imagined when it decided on the 2019 sanctions.

In that sense, I think very few people have bothered to really look at the presentation slides because the heart of the breakthrough is hidden elsewhere from the marketing concept of the tau scaling law—it’s in a technical detail that only a few specialized engineers have noticed (which I went digging into, haha). There’s apparently a bonding process between silicon layers with a spacing smaller than 2 micrometers, which turns the vertical wires connecting the different layers of the same chip into full-fledged computation paths. They’re mastering true 3D integration while the rest of the world is still reasoning on a single horizontal plane.

For me, the best image is that of an architect building a tower while his competitors keep sprawling individual houses horizontally. Intel and TSMC are fighting to etch ever tinier transistors because their EUV lithographies lock them into that logic. Huawei, cut off from those lithographies since 2019, chose a different battle: shortening to the maximum the time an electrical signal takes to travel through the entire system—this duration they call tau, which they minimize simultaneously at the component level, the circuit, the chip, and the complete machine. It’s real physics presented at the world’s most serious IEEE conference on the subject.

By the way, the numbers are thought-provoking—go take a quick look and you’ll see that transistor density rises from 126 to over 400 million per square millimeter between 2024 and 2031, core frequency climbs from 2.6 to 5 gigahertz, even full-system performance jumps x125 in 4 years between 2026 and 2030. And above all, 381 chips have already been mass-produced using these principles since 2020, which means they started shifting paradigms right from the first wave of U.S. sanctions—6 years of quiet work while Western analysts thought they were in survival mode, lol. What everyone took for resistance was actually a deliberate strategic pivot carried out with the patience of a people that plans 50 years ahead (that long-term vision of China I often talk to you about).

I’ve been repeating it to you here for years: Western sanctions are accelerating China’s industrial and tech policy instead of slowing it down—they force it to invent the world of tomorrow while the West stays stuck in the one from before. And just for info, even BYD created the LFP battery in response to the nickel blockade, and now it dominates the global electric car market. DeepSeek designed its multi-head latent attention architecture in response to the H100 chip blockade, and it slashed the cost of large language models by a factor of 10. Huawei just laid down LogicFolding and tau scaling in response to the EUV blockade, and it’s already reshaping the global semiconductor trajectory through 2031.
