So far I have not found the science, but the numbers keep on circling me.

NEW ANALYSIS: China's CO2 has now been 'flat or falling' for 21 months
* Down in 2025
* Still below Mar 2024
* Clean energy wave a key factor
If this is China's peak (TBC) it's the climate story of the century so far…

One year, and we're on the brink of war with the rest of NATO. God help us after three more years of this.

I'm not really sure how to square this with the US spending 1% of GDP on datacenter construction.
The US is losing blue-collar jobs for the first time since the early pandemic—year-on-year job losses have hit 145k as manufacturing, transportation, & mining industries lose jobs at a rapid pace while growth in construction has nearly zeroed out

If anyone DMed me recently - to use DMs for this app in the UK, I have to go through age verification, which I have not done yet on principle. If you are trying to reach me privately, email or Twitter DM works.

Excited to share our latest preprint, on using deep learning to extract the weird fractional quantum statistics of 2D topological materials: arxiv.org/abs/2512.15872
Extracting Anyon Statistics from Neural Network Fractional Quantum Hall States
Fractional quantum Hall states host emergent anyons with exotic exchange statistics, but obtaining direct access to their topological properties in real systems remains a challenge. Neural-network wav...

A Generalized Bias-Variance Decomposition for Bregman Divergences
The bias-variance decomposition is a central result in statistics and machine learning, but is typically presented only for the squared error. We present a generalization of the bias-variance decompos...

I think that we should all strive to live our lives in such a way that, when we die, our greatest accomplishments are not overshadowed by constant bickering about exactly how racist or sexist we were.

I think every one of my ML colleagues from a decade ago who stayed in academia and avoided the AGI/LLM race is now doing "AI for science". Really feels like those are the only two options left.

I feel like these Catholic converts who think they can argue with the Pope just did not do their research. If they want a religion where they can argue nonstop with everyone, up to and including God, they would obviously be better served by converting to Judaism.

Joel is on a mission to get the EA/rationalist set to embrace Rortyian pragmatism. It's a tough job but someone's gotta do it.
[1/9] Excited to share our new paper "A Pragmatic View of AI Personhood" published today. We feel this topic is timely, and rapidly growing in importance as AI becomes agentic, as AI agents integrate further into the economy, and as more and more users encounter AI.

If things become so polarized that anything "AI", no matter how broadly construed, becomes knee-jerk associated with the Trumpian right wing, I should probably just kms. www.axios.com/2025/10/31/m...

This climate is ripe for an anti-AI socialist to emerge as a counter to Trump.

I can't believe how fast they went from "removing this cookie-cutter statue is erasing history" to "well, the East Wing was kind of shabby anyway".

Even the Jacobins didn't tear down Versailles. They sold off the furniture and let it fall into disrepair, but they didn't just knock down a whole wing.

Trump basically forgot about the whole annexing Canada thing after like three months and hasn't mentioned it in ages, but America's reputation in Canada has been destroyed for a generation. Just one of a million sad stupid pointless things from the last year.
