Nine more lessons from my 3D book about energy, now covering the whole GCSE energy topic: kinetic, gravitational and elastic energy, heating, power, efficiency, energy resources and conservation of energy. Built with Opus 5.5 and Three.js. The full book ↓

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

Now THAT is a reframe.

2024 年科学家们定义了一种新的几何形状“软胞” (Soft Cells)，可以无缝的填充整个空间，我对其中以截角八面体为骨架的形状特别感兴趣：边变成圆弧，面是极小曲面，具备对称美感。 昨天让 ChatGPT Pro 读论文建立数学模型，Codex 接手 CAD 建模，然后 3D 打印机打印出来，心想事成言出法随的好时代啊。

I gave my Grok bot $1000 to build itself a body. Parts just keep showing up at my apartment.

Snímek složený z 578 jednotlivých 8sekundových expozic pořídil 📷Brendan Larsen 9. září 2026 mezi 20:18 a 22:13 místního času nedaleko novozélandské sopky Mt. Taranaki. Na snímku je 14450 stop po přibližně 1400 jednotlivých družicích.

Consider: millions of years ago our antecedents gave a massive sacrifice of their left hemisphere. We lost a tremendous amount of short term memory and replaced it with Broca’s, Wernicke & the phonological loop. But why? So we can—talk. Thus chimpanzees can do this—we can’t:

With the Man, Ron Conway.

1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness. New preprint: biorxiv.org/content/10.64898… (led by @HesseJanis, with @FrankLanfranchi, @_conor_mcgrory, @Yuelin_Shi, and @EngelTatiana)

Wilderness years are a recurring motif I wonder if anyone’s studied them. Why are they so common?

Going forward, all advertising on 𝕏 will be subject to a reasonable esthetic standard. Advertisers who post ads that are ugly, shrill, strident or overstate claims about their product will be barred from advertising.

This is hands down the best explanation of meditation I've ever seen 🤯

interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works already-clean.goodfire.com/
