<p>> It's part of my eternal quest to find the memory safety holy grail: something as powerful as Rust's borrow checking, yet something as simple and flexible as reference counting or garbage collection.<p>I'm definitely hoping you succeed.  I'd love to be able to write a small language (maybe that didn't do absolutely every last thing you can do in Rust, but was ergonomic and easy to use) that had a borrow checker and didn't require writing a nuclear reactor.</p>

<p>> Given the geopolitical concerns from both the east and the west, this makes the question of whether Europe should move content off of US infrastructure a lot more complicated.<p>I mean, if Russia is striking datacenters in London/Dublin/Frakfurt/Paris/Amsterdam, then we've got really big problems.<p>And is the US even allied to Europe, or is Europe going it on their own?  They might do better to move to datacenters in China at that point.<p>Barring that kind of a situation, moving European data back to Europe makes the most sense.<p>Putting datacenters in the Baltic states might not make the most sense, tho.</p>

<p>Yeah, it still is.

You won't see any rioting in the streets due to this.<p>The point is to inflict economic harm on the elite around Putin--the owners of Yandex, the other companies using those datacenters, etc.<p>The point is not to take out the average Russian's internet search index.<p>A more important goal is for these strikes to get headlines and serve as Western-facing propaganda, with "hitting Russia's Google" and "hitting Russia's Amazon" being easily digestible for those in Europe and America.  That still beats the effect this will have on the average Russian.<p>Russia isn't a Western Democracy.</p>

The USSR told Vietnam where B-52s were heading so they could evacuate military leaders and get other military units out of the way.

<p>On the other hand, I get mentally exhausted reading AI slop over and over again.<p>My brain can't help itself in looking for AI tells and gauging if writing sounds like AI or not.<p>Then once it latches onto the idea that the writing is probably AI, then it feels like half my brain is just reading the text looking for the AI smells.<p>Calling it "AI smells" like "code smells" might actually be what is going on in my brain, and I start code reviewing it at that level rather than reading it for what it does.<p>I really would prefer people not just post slop.

<p>In addition to those issues that the wife in the story raised, here's some meta-analysis of the Navier-Stokes result that puts all of these solutions into question:<p><a href="https://arxiv.org/abs/2610.08144" rel="nofollow">https://arxiv.org/abs/2610.08144</a><p>> Autoformalisation is increasingly used to verify mathematical texts, including those generated by AI, as in OpenAI's announced proof of blow-up of solutions to the Navier-Stokes equations. In this process, an AI system translates the text from a natural language (NL) into a formal language such as Lean. Once this translation is done, the argument expressed in the formal language can easily be mechanically verified. The purpose of this article is to demonstrate why this process may offer no confidence in the original NL argument, owing to the various difficulties in performing the translation semantically faithfully. In particular, we highlight that the problem of resolving ambiguities in mathematical NL text, which is necessary in order to provide semantically faithful translation, is arbitrarily high up in the Solvability Complexity Index (SCI) hierarchy/arithmetical hierarchy (the SCI =∞). Hence, informally, providing semantically faithful AI autoformalisation is harder than any computational problem including the Halting problem (which has SCI =1). To demonstrate the effect of this result we provide several examples of AI mistranslations of NL statements and proofs into Lean in practice, resulting in mismatches between NL proofs and their Lean `verifications'. 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.<p>And I don't think that paper addresses it, but if the LLM can find a bug in Lean and exploit it to prove something, there's a good chance it will find it and not report it.  So if you've got some million-line proof in Lean, spit out by an LLM, you still can't quite trust it, even after validating the problem transcription.<p>(This is the same category of problem as the huggingface hacking incident, where the LLM finds and exploits an unintended cheaty loophole)</p>

<p>> So, yes, we could've measured c wrong.
