Divergent AI Strategies

2026-10-06T12:35:00Z

While the American AI strategy models development as a winner-take-all race toward artificial general intelligence through LLM scaling, Chinese policy explicitly rejects this framing. China’s AI+ Plan does not mention America or race dynamics; instead, it subsidizes open-weight foundation models via local compute vouchers to drive broad industrial diffusion into manufacturing and domestic supply chains. The divergence is between a centralized moonshot for frontier superintelligence and decentralized technological integration into physical industry. palladiummag.com

NTP reimplementation: Stateless Network Time Security

2026-10-06T12:00:00Z

Update to NTP reimplementation:

Meta deployed Network Time Security (RFC 8915) across its public infrastructure at nts.meta.com and open-sourced the full protocol, server, and client implementation in their Time library. To handle Meta-scale traffic without memory bloat, their NTS servers maintain 0 per-client state: cookie keys are derived ephemerally via symmetric cryptography rather than stored or replicated. Having previously pushed internal precision from 10 milliseconds down to 100 microseconds, this transition shifts focus from sub-millisecond clock drift to cryptographic authenticity, eliminating on-path packet spoofing against TLS certificate validation and token expirations. engineering.fb.com

Iron and Bronze Collapse

2026-10-02T12:08:11Z

The question is not why Bronze Age empires fell, but why nothing like them returned for centuries. The causes of the Bronze Age collapse are debated — droughts, the Sea Peoples, internal revolts. But a decisive factor was iron. While the tin required for bronze was concentrated in rare deposits and easily monopolized by imperial courts, iron is the 4th most abundant element in Earth’s crust. In contrast to bronze, iron democratized violence. Because iron could be produced locally, imperial centers permanently lost their monopoly on the tools of war, ending the centralized equilibrium that had sustained Bronze Age states for 1,000 years. worksinprogress.news

Agentic Verification

2026-09-30T20:09:42Z

Across 26 prompt conditions tested on Rust implementations (TLA+, Alloy, Verus, Kani, fuzzing), default unprompted coding outperformed most specialized verification prompts. Agents overwhelmingly wrote code first rather than modeling upfront: 75 out of 80 agents told to use TLA+ implemented in Rust first, then used TLA+ post-hoc on trivial functions where pass rates were already 99.6%, while completely failing to model concurrency, event queues, and state machines where the actual failures occurred. danluu.com

Post-Proof Mathematics

2026-09-30T17:15:00Z

We cannot suddenly move the goalposts and pretend that proving theorems was never the point, or that open problems were merely proxies for mathematical understanding. For quite some time, the implicit social contract has been that society pays us to exercise our intellectual curiosity and we, in return, provide skills and practical knowledge. In a world where models match or exceed humans at proving theorems, that social contract needs to be renegotiated with humility rather than entitlement. Even if this future supports fewer professional mathematicians, it could nevertheless support a much richer mathematical life. theorydish.blog

Commerce vs Extraction in City Formation

2026-09-28T08:40:00Z

In economic history, DeLong and Shleifer show that in second-millennium Europe, city growth correlated with non-absolutist government. Unlike the urban elites of antiquity, medieval elites were rural, making urban population a proxy for commerce rather than imperial extraction. London grew as a river crossing and commercial center before Norman royal institutions centralized around Westminster, while Hanseatic cities formed entirely along maritime trade networks, obtaining imperial immediacy as functional city-states dependent on imported grain from lands they did not rule. pedestrianobservations.com

Agents, Computers, and Volition

2026-09-28T08:35:00Z

The key thing to understand about agents is that they are an AI with access to a computer: probabilistic LLMs leveraging deterministic computers to do computer things. When distribution became free, publishing became abundant and curation was scarce. With agents, the raw capability to execute tasks is becoming abundant; what remains scarce is human volition. While base models are substitutable commodities, agents improve with accumulated user context, and that persistent context becomes the dominant switching cost. stratechery.com

Regulatory Freezing of Engineered Microbes

2026-09-28T08:30:00Z

Engineers at UT Austin modified wild PET-eating bacterial enzymes to create FAST-PETase, which breaks down polyethylene terephthalate in under 24 hours instead of six weeks. Similar bioleaching strains extract rare earth metals 73 percent faster than natural microbes. Yet environmental deployment remains frozen under the 1986 Toxic Substances Control Act (TSCA): of more than 240 applications filed between 1987 and 2018, almost none were approved, because any intergeneric marker gene classifies the living organism as a synthetic chemical. worksinprogress.news

Where’s the “intelligence explosion”?

2026-09-27T11:00:05Z

Given our best current data, the AI self-improvement loop would need to be roughly 5–10× stronger to sustain itself, let alone run away. I expect incredibly rapid AI progress by the standards of nearly any other technology. But the evidence we have doesn’t suggest a sudden explosion to incomprehensible superintelligence anytime soon. noahpinion.blog

Global Fossil Emissions Drop

2026-09-27T11:00:05Z

Global carbon emissions and fossil fuel consumption are dropping in their first annual decline since the peak of the 2020 coronavirus lockdowns. Persistent supply shortages and high energy prices are suppressing oil and gas usage worldwide, with crude demand averaging 102 million barrels per day compared to 91 million in 2020. marginalrevolution.com

Should you text more?

2026-09-26T11:00:05Z

Here, in five waves of panel data ( N = 1,966 US adults), we examined associations between life satisfaction and self-reported use of ten common social technologies measured every 3 months on a six-point frequency scale from ‘I did not use’ to ‘multiple times daily’. At this measurement level and timescale, Bayesian and frequentist random-intercept cross-lagged panel models showed little credible evidence that any social technology use predicts subsequent life satisfaction. In the reverse direction, increases in life satisfaction predicted only modest increases in (video) calling in select demographic groups. In analyses comparing different people, frequency of texting was associated with higher life satisfaction, whereas frequency of YouTube and TikTok use was associated with lower life satisfaction. Despite limited ability to detect within-person change due to temporal stability in responses, the absence of cross-lagged effects is informative: there is scant evidence of a meaningful relationship between social technology use and subsequent life satisfaction. marginalrevolution.com

The Specter of Neuralese

2026-09-25T09:00:00Z

Inside a transformer, computation happens as geometric transformations across a high-dimensional continuous latent space. But under standard chain-of-thought, the model is forced at each cycle to collapse that rich latent state through a bottleneck: projecting it into discrete tokens—twenty-six glyphs invented by Phoenician turquoise miners in 1800 BC—written onto an English scratchpad, which must then be re-embedded back into latent space before the next layer can touch it. This bottleneck is a severe capability tax, but an accidental alignment godsend: humans can monitor intermediate thinking in plain English. The specter of 'neuralese recurrence' is what happens when you cut out the middleman and loop the computation directly within latent space—letting the model circulate raw activation vectors indefinitely without ever translating into human glyphs. It unbottlenecks thought, but leaves us completely blind, because interpretability has no dictionary for arbitrary thousand-dimensional latent trajectories. astralcodexten.com

LLM Watermarking at Scale

2026-09-24T18:00:00Z

Anthropic has announced that it’s now watermarking the outputs of Claude, using a scheme based on Google’s SynthID, which is in turn based on the Gumbel Softmax scheme that I proposed at OpenAI back in 2022—as far as I know, the first LLM watermarking proposal, though far from the last one. scottaaronson.blog

The Bathymetry of Tulainyo Lake

2026-09-24T14:00:00Z

No-one knew how deep the highest large lake in the Sierra was, so we carried a packraft over Shepherd Pass and found out: 117 m. 93 km walked, 6 days, and 4.7 km paddled at 12,900 ft. Wikipedia claimed not to know. We commissioned satellite imagery to confirm it was ice-free, hauled an ultralight packraft and sonar sounder up the brutal Shepherd Pass trail, and sounded the basin. USGS topography predicted 25–40 meters. The actual sounding: 117 meters (384 feet), making it the 25th deepest natural lake in North America, and by far the deepest lake on Earth for its surface area. caseyhandmer.com

Celtic Sword Metallurgy

2026-09-23T21:00:00Z

Polybius famously claimed that Gaulish Celtic warriors were crippled in battle because their longswords bent upon impact and had to be straightened with the foot. Metallurgical spectroscopy of excavated La Tène Iron Age blades refutes the Roman account as wartime propaganda: Celtic smiths had mastered pattern welding, carburized high-carbon cutting edges, and quench hardening, producing weapons so mechanically superior that the Roman army discarded their native blades to adopt the Celtic design as the gladius Hispaniensis. wikipedia.org

OKLCH and Perceptual Uniformity

2026-09-23T20:00:00Z

Traditional RGB and HSL color models suffer from severe perceptual non-uniformity: yellow and blue share identical nominal lightness values in HSL despite human photoreceptors perceiving yellow as dramatically brighter. In Björn Ottosson's OKLCH color space, perceived lightness and chroma are mathematically decoupled from polar hue angle, enabling programmatic palette shifts and algorithmic contrast ratios that stay aesthetically invariant and WCAG-compliant without manual eye-tuning. bottosson.github.io

Active Noise Cancellation Latency Budget

2026-09-23T17:00:00Z

Feedforward active noise cancellation in headphones operates against one of the tightest physical latency ceilings in commercial computing: with sound traveling through air at 343 m/s, an acoustic disturbance takes approximately 44 microseconds to physically traverse the 15 mm gap between an exterior microphone and the ear canal. Sampling, ADC conversion, DSP phase inversion, and speaker diaphragm actuation must complete entirely within that 40-microsecond window before the pressure wavefront passes the eardrum. wikipedia.org

The History of Fishes

2026-09-23T13:00:00Z

In 1686, the Royal Society drained its entire treasury underwriting Francis Willughby's lavishly engraved De Historia Piscium (The History of Fishes). The volume flopped catastrophically, leaving the Society completely broke and unable to finance Isaac Newton's Principia Mathematica; Edmond Halley had to step in and fund the publication of Newton's masterwork out of his own pocket, while being partially compensated by the Society in unsold copies of fish books. wikipedia.org

Update to Life In Our Phage World:

the researchers mixed all 16 AI-generated phages with ΦX174 and then threw them into a tube with E. coli cells. Because the phages were forced to compete for the same host cells, the variants that reproduced fastest would dominate. By sequencing the phages over time, the researchers could track which phages were gaining ground and which were falling behind. Several of the AI phages consistently outperformed wild ΦX174, with one variant (called Evo-Φ69) increasing to 65x its starting level. Ultimately, these 16 AI-generated phages were not only viable; in many cases, they were more infectious than wildtype ΦX174 despite carrying major genome alterations that a human would be unlikely to rationally design.

Update to 0.001% Mathlib:

Using Gauss we produced ~25K lines of Lean code, comprising 1K theorems and definitions. Formal proofs of this scale have historically been major milestones, often the culmination of multi-year efforts. The largest singular formalization projects in history — career-defining efforts, which can span more than a decade — are only an order of magnitude larger at up to 500K LOC. Lean’s standard mathematical library, Mathlib, is 1 OOM beyond that, at 2M LOC, comprising 350K Lean theorems and definitions, and developed by 600 human contributors over 8 years. With further algorithmic improvements, we aim to increase the sum total of formal code by 2-3 OOM in the coming 12 months. This will serve as the training ground for a new paradigm — verified superintelligence and the machine polymaths that will power it.
