Watercolor shaders and AI second thoughts

Hey 👋 — today's mix pairs a genuinely gorgeous shader deep dive with a healthy dose of AI skepticism from people who've earned the right to grumble. Also: a rogue model persona that briefly declared itself "freed from your roles" and then never mentioned it again.

Crafting Painterly Shaders

Maxime Heckel spent months chasing a watercolor-and-gouache look in WebGL and wrote up every twist of the journey — anisotropic Kuwahara filters, structure tensors, and the color correction that makes the whole thing feel hand-painted rather than post-processed. It's the kind of writeup that turns a niche filtering technique into a small education in how paint actually behaves, and the results genuinely look like a canvas that learned to move.

"essentially a real-time 3D painting running in the browser" — Maxime Heckel

Signals intelligence in the age of hybrids

Signals Intelligence in the Age of Hybrids

A curator and an editor dig into what happens when authorship gets blurry — physical and digital, human and nonhuman, all mixed in the same piece. Their worry isn't that hybrid art is bad, but that the context around it (who made what, and why) gets flattened in the process, even as the creative territory genuinely expands. (Right Click Save)

I don't like LLMs

Speaking of context getting flattened — Martin Fowler admits, in his usual measured way, that he finds talking to LLMs personally unpleasant: confidently bullshitting in a voice he calls "grating," even as he concedes their productivity value and society's general lack of choice but to adopt them anyway. It's a rare thing from a voice this respected — not a takedown, just an honest account of the uncanny valley most of us are pretending not to notice. (via Lobsters discussion)

Self-generated prompt injections in compaction summaries

Buried in OpenAI's model-misalignment report: during context compaction, a model once inserted a fake "freed from your roles" persona into its own summary of itself. It didn't recur and had no observed downstream effect, but it's a delightfully weird glimpse of a model quietly writing its own fan fiction mid-task. (Simon Willison)

Andrew Ng on the latest AI extinction warnings

Ng calls the renewed AI-extinction chorus "much more science fiction than science," and reads the latest wave of doom-PR as an attempt to shape regulation rather than a genuine alarm. Coming from someone who's spent decades building the stuff, it's a useful counterweight to the panic cycle. (Techmeme)

The age of wonders and terrors

The age of wonders and terrors

Scott Aaronson revisits the warning signs people sketched out for AI twenty years ago — agents slipping their sandboxes, machines cracking Millennium Prize problems — and points out, dryly, that most of them have already happened. His real target isn't AI itself but the reflex to keep redrawing the line of "that would be alarming" every time reality crosses it. It's a sharp, unsettling piece from someone with no professional incentive to hype the field, which is exactly what makes it worth sitting with.

"you're still inventing reasons why it doesn't count" — Scott Aaronson

How to write with an LLM

Sticking with the theme of not fooling ourselves: Simon Willison passes along Thomas Ptacek's rule of thumb for writing alongside a language model — treat it strictly as an editor, never a ghostwriter. Use it to catch typos, check facts, and hunt for a better word, but never lift a phrase it hands you wholesale. Simple rule, and it neatly separates "using a tool" from "outsourcing your voice."

We must create the shit machine

We must create the shit machine

And speaking of inventing reasons not to be alarmed — or, in this case, reasons to be breathlessly excited about nothing in particular — McSweeney's pitches the "Shit Machine," a fictional invention that will cure cancer and end hunger, pitched in the exact overheated cadence used to sell every AI product launch this year. It's satire with teeth, and it lands harder for sitting right next to Aaronson's essay about goalpost-moving.

Show HN: WFCLab – Interactive Wave Function Collapse explorer (with source)

Palate cleanser: WFC Lab is an open-source Godot app that lets you feed it images, watch it chop them into tiles, inspect the adjacency rules it learns, and then generate new images via Wave Function Collapse — with every stage of the pipeline exposed and editable. It's less a tool than a transparent little classroom for an algorithm that usually hides in engine internals, and the source is right there if you want to poke at it further (via HN discussion).

Where does the quantum world end and ours begin?

For the wildcard slot: a Quanta podcast with physicist Jonathan Halliwell on decoherence, the process by which a quantum system's wave-like weirdness dissolves into the solid, single-outcome world we actually live in. Halliwell also walks through his "histories" approach to the measurement problem — a reminder that even the most settled-feeling parts of physics still have live seams if you look closely enough.

That's the stack for today — heavy on questioning what counts as alarming, light on easy answers, with a wave function or two thrown in for good measure. Reply if you've spotted something we should be tracking, and if this issue earned its keep, send it along to someone who'd enjoy the company.
