“Goebbels was in favor of free speech for views he liked. So was Stalin. If you’re really in favor of free speech, then you’re in favor of freedom of speech for precisely the views you despise. Otherwise, you’re not in favor of free speech.” ― Noam Chomsky #freespeech

Timely for SA's election results: an argument for single-member ranked-choice voting systems like Australia's. "Highly polarising candidates may attract strong first-choice support but often struggle to gain the second or third preferences needed to win." socialeurope.eu/proportional-r…

@0xcheddar_ @PamelaBies I'm about to live on a rural property, complete with chickens. And I know enough about small-scale farming to know it's a *very* harsh life: huge amounts of work for very thin margins. (BTW, this has nothing to do with the specifics of our financial system.)

@SwellGibson @PamelaBies Perhaps we should stop focusing on efficiency and competitiveness and instead motivate ourselves by providing healthy food for our local communities and families.

Remarkable thing about Paul Ehrlich is not just how wrong he was but that we was totally unphased and unchastened by his wrongness, just a total epistemic disaster zone — a pattern of conduct that is unfortunately shared by many prominent people from different schools of thought.

Terence Tao explains the math behind today’s LLMs is actually simple. Training and running them mostly uses linear algebra, matrix multiplication, and a bit of calculus, material an undergraduate can handle. We understand how to build and operate these models. The real mystery is why they work so well on some tasks and fail on others, and why we cannot predict that in advance. We lack good rules for forecasting performance across tasks, so progress is largely empirical. A key reason is the nature of real-world data. Pure noise is well understood, perfectly structured data is well understood, but natural text sits in between, partly structured and partly random. Mathematics for that middle regime is thin, similar to how physics struggles at meso-scales between atoms and continua. Because of this gap, we can describe the mechanisms but cannot yet explain capability jumps or give reliable task-level predictions. That mismatch, simple machinery versus hard-to-predict behavior, is the core puzzle. ---- Video from 'Dr Brian Keating' YT Channel (Link in comment)

Terence Tao on AI in Math. AI can synthesize a million papers and brute-test ideas. Humans can check just 5 examples and see the pattern. But as systems move toward world models, causal reasoning, and active learning, this efficiency gap will narrow.

@ellymelly If you ask people casually, how wins in a 3 way vote, they will always instinctively say the one with the most votes, but when it comes to politics of course the losers find a way to twist this around.

"The information that such decision-makers depend upon requires extremely thorough testing. Openly deliberating about these matters brings epistemic advantages, therefore, as well as legitimacy." 2/2

A supposed Chinese startup has just made US warfare operations visible to Iran simply by publishing carefully-labelled data as open-source information. A commercial satellite operator did this to Ukraine's advantage in 2022, too. Another new change in warfare.
Shanaka Anslem Perera ⚡@shanaka86

BREAKING: A Chinese AI startup called MizarVision is publishing high-resolution satellite imagery of every US military base, every carrier strike group, every F-22 deployment, every THAAD battery, and every Patriot missile position in the Middle East. Labelled. Geolocated. AI-annotated. Updated in near-realtime. Shared by PLA-linked accounts and Chinese state media to an audience of billions. The first major release came on 20 February, eight days before Operation Epic Fury began. MizarVision published images showing US aircraft transfers to Ovda Airbase in southern Israel, fighter deployments across Saudi Arabia and Qatar, and naval buildups in the Arabian Sea. By 1 March, the releases had expanded to include detailed imagery of bases in Jordan, Kuwait, Bahrain, and the UAE, with AI labelling identifying specific aircraft types, air defence configurations, and troop concentrations. One release catalogued approximately 2,500 individual US military assets across the region. The imagery comes from two sources. The first is China’s Jilin-1 satellite constellation, a network of over 100 commercial Earth observation satellites operated by Chang Guang Satellite Technology, whose data is used by the PLA. A majority of Jilin-1 satellites are dedicated to regional imaging with sub-metre resolution, capable of identifying individual aircraft on tarmacs and distinguishing between THAAD and Patriot battery configurations from orbit. The second source is commercially available Western satellite data from providers like Maxar and Airbus, which MizarVision aggregates, processes through proprietary AI models for automatic target recognition, and republishes with military-grade labelling that transforms raw imagery into actionable intelligence products. The Pentagon has downplayed the releases as “open-source.” This framing misses the point entirely. The value of MizarVision’s output is not the raw satellite image. Any government can purchase commercial satellite passes. The value is the AI processing layer that converts terabytes of imagery into labelled, searchable, cross-referenced intelligence products at a speed and scale that previously required the resources of a national intelligence agency. MizarVision is democratising military surveillance and publishing the output on social media where Iran’s 31 autonomous IRGC provincial commands can access it from a mobile phone. No direct evidence confirms classified data transmission from Beijing to Tehran. But the distinction between “classified” and “publicly shared AI-processed satellite intelligence identifying every US military asset in the Middle East by type, location, and configuration” is a distinction without a meaningful difference to a provincial IRGC commander selecting his next target. The strategic implications extend far beyond this conflict. In the 2022 Ukraine war, Maxar’s commercial satellite imagery aided Kyiv by exposing Russian deployments. The West celebrated it as the democratisation of intelligence. China has now executed the identical playbook in reverse: a nominally commercial firm, with documented PLA data-sharing arrangements, publishing intelligence products that expose American deployments during an active war. The precedent is set. Commercial satellite intelligence is now a weapon of great-power competition deployed through AI startups with plausible commercial deniability. MizarVision has fewer than 200 employees. Its AI models run on commercially available hardware. Its satellite data comes from constellations any nation can build. And it has just demonstrated the capability to map every US military asset across an entire theatre of war and publish the results on the open internet before the first bomb falls. The next war will not begin with a missile launch. It will begin with an AI model labelling every target from orbit. Full analysis - open.substack.com/pub/shanakaans…

I see folks are pledging not to use AI in their writing. I pledge the opposite: I will use the latest LLMs, and for that matter any other tool, to best improve my research or the way I communicate it. That way, if my name is on it, you can be sure it reflects my own best judgment

An Iranian man left this comment on my YouTube channel. This is without a doubt the single best explanation of the reality facing Iranian people today👇 "As an Iranian, I can tell you the situation is no longer just political—it's existential. We are trapped between two collapsing structures: one internal, one external. On one hand, we face a deeply dysfunctional government, led by the Supreme Leader and the Islamic Republic’s unelected institutions. Decades of economic mismanagement, suppression of dissent, and brutal ideological control have alienated multiple generations. No one believes in reform anymore—because every attempt has either been co-opted or crushed. But here's the paradox: We are also terrified of regime collapse—because we've watched the aftermath of Western intervention in countries like Iraq, Libya, Syria, and Afghanistan. Each was promised freedom; each descended into chaos, civil war, or foreign occupation. So no, we don't trust the U.S. or Israel. Not because we support our regime—but because we know how imperial powers treat ‘liberated’ nations in the Middle East. Freedom, in their language, often means vacuum, fire, and permanent instability. Right now, many Iranians live with three truths at once: The Islamic Republic is morally and politically bankrupt. The alternatives offered by foreign actors are not liberation—they’re collapse. A bad government is survivable. No government is not. We are not silent because we agree. We are cautious because we’ve learned—too well—what happens when superpowers decide to "help." In a sentence: Iran is a nation held hostage by its own regime, but haunted by the fate of its neighbors. We are stuck in a house we hate, surrounded by fires we fear more."
