“[...] These include OpenAI’s announced Navier-Stokes proof. In particular, we show that the formalised Lean proof does not correspond to the NL proof of blow-up of solutions to the Navier-Stokes equations” 😂 – arxiv.org/pdf/2610.08144 via @struan.exo.org.uk

That’s outrageous, Shannon. I don’t know if this helps, but it’s inconceivable to me, that they might come close to matching your knowledge, insight, or talent and skill for writing. I recommend *your* book often. Meanwhile, there’s a lot of bad books out there.

Will “The Lean proof that OpenAI provided isn’t the same as their printed proof, so who knows if any of it is actually right” get as much publicity as the original PR, I wonder. The final 20% is 80% of the work. Whether it’s a website, a Photoshop knock-off, or a Millennium prize problem
Example 3.1 (The NL paper claims a stronger inverse estimate than the cited Lean formalisation). Figure 3 concerns the estimate in Lemma 8.6, equation (8.19), of OpenAI’s Finite time blowup for Navier–Stokes. We compare this estimate with the cited Lean declarations at commit f9e8bc5 (click to see the documentation on Github). The issue is a change in the order of the input derivatives required to bound the output derivatives. In particular, we have the following discrepancy. With m a nonnegative integer, the comparison in Figure 3 is
NL paper, equation (8.19): ∥N−1F∥Cmy ⩽ Cm∥F∥Cm+4y, (3.1)
Lean Estimate: ∥N−1F∥Cmy ⩽ Km∥F∥Cm+5y. (3.2)
Summary: The Lean code produced by OpenAI often has stronger conditions on bounds on the derivatives of various functions than the corresponding results in the NL paper.

One use of AI I have no trouble with is restoring lost online projects. You can tell it to go and look them up on archive.org and then rebuild them in a new location. Also fixing legacy stuff. Do you have a whole bunch of archives that are in the wrong format or are broken? Get an AI to fix them.

Not a single perspective here from someone who didn’t write the report. This isn’t journalism, it’s an author’s abstract. Every para is just “this is what the paper says.” It’s exactly what you would get if you asked an undergrad to read it and write a summary. Or get one from a chatbot.

But, as an archivist, I must say that we are not just throwing our hands up and wailing about it. As a profession we are getting on with finding methods and systems so that digital records do endure. And it’s a little dispiriting when the media periodically repeats the ‘Digital Dark Age’ story.

Impact
Alt text: A six-panel comic about a small white ghost haunting a table lamp. The ghost says, “I’m the ghost of this lamp. Just this lamp.” It reflects that it could have haunted “something bigger. A room. A house,” but chooses to “focus my craft” where its impact is “small but does not go unnoticed.” The lamp suddenly clicks on by itself. In the next panel, a confused man asks, “Who turned on this lamp?” while the ghost peeks out from behind the table. The final panel shows the ghost hiding beside the table with a pleased smile as the lamp glows.

Listening to Schubert’s Impromptus, D.935, played by Radu Lupu. This is very beautiful music. Hard to explain, but Schubert somehow mixes events and memories: “let’s dance” -> “remember when we danced”, “let’s talk” -> “remember when we talked” and so on. Schubert had a tender soul.
