  • Sure, it’s hard to say whether a computer program can “know” anything or what that even means. But the paper isn’t arguing that. It assumes very little about how how LLMs actually work, and it defines “hallucination” as “not giving the right answer” with no option for the machine to answer “I don’t know”. Then the proof follows basically from the fact that the LLM-or-whatever can’t know everything.

    The result is not very surprising, and saying that it means hallucination is inevitable is an oversell. It’s possible that hallucinations, or at least wrong answers, are inevitable for different reasons though.



  • Yes, but it doesn’t matter, these people don’t read the Bible.

    They do read the Bible though, at least in my experience. I’ve gone to a number of different churches, Evangelical and otherwise, and the Evangelical or otherwise Calvinist folks were the ones that read the Bible the most and in the most detail — but perhaps also the ones who came to horrible conclusions the most often. Like that you should shine the light of Christ into the world by blocking women for promotion at your job, because 1 Tim 2:12 says that Paul does not permit them to have authority over men. (Real example, if possibly the worst one I’ve seen.) Maybe my experience is not representative, but I don’t think the problem is primarily that Evangelicals don’t read the Bible.

    I have a long theory about some of the ways that Evangelicalism distorts Scripture, but one root of the issue is that (IMHO) Scripture was written by humans, reflects the biases of the authors and their societies, and has a lot of horrible things in it. If you take a sola scriptura view and then read it through a lens that’s been cultivated over years to reinforce patriarchy and supremacy (see e.g. Manifest Destiny, the curse of Ham, etc) then you will end up absorbing the genocidal and supremacist bits and not the hospitable and altruistic bits.

    For them, it’s just an excuse to do whatever it is they’re doing.

    For sure. People don’t want to repent. They want to find justifications for what they were already doing, or planning to do.


  • I was having a weird one today so I read through the book of Amos. It’s shockingly similar to the current situation.

    Amos prophesied that Gaza would be destroyed, even genocided, as a reaction to crimes that included kidnapping entire communities. But that’s just an intro to a prophecy that Israel would be violently and mercilessly destroyed in response to a long list of their own crimes.

    I’m not saying that Amos predicted the current situation, just that it’s sad how little we’ve improved in 2500 years.


  • So I wrote a long-ass rundown of this but it won’t post for some reason (too long)? So TLDR: this is a 17,600-word nothingburger.

    DJB is a brilliant, thorough and accomplished cryptographer. He has also spent the past 5 years burning his reputation to the ground, largely by exhaustively arguing for positions that correlate more with his ego than with the truth. Not just this position. It’s been a whole thing.

    DJB’s accusation, that NSA is manipulating this process to promote a weaker outcome, is plausible. They might have! It’s a worrisome possibility! The community must be on guard against it! But his argument that it actually happened is rambling, nitpicky and dishonest, and as far as I can tell the other experts in the community do not agree with it.

    So yes, take NIST’s recommendation for Kyber with a grain of salt. Use Kyber768 + X448 or whatever instead of just Kyber512. But also take DJB’s accusations with a grain of salt.




  • He’s not just ignoring it though: he’s been advancing and legislating (many of) these awful policies for literally fifty years. You might quibble about where to draw the line between “fascism” and “everyday atrocities”, but the guy has done a lot of harm in his life.

    That’s not to say that everything he’s done has been bad. And I’d still rather have him in government than one of today’s fully mask-off GOP fascists: there’s no doubt that this label applies to Trump or DeSantis. But it’s important to recognize that neither party has any interest in ending many of the US’s worst crimes. We’re going to need some major … let’s optimistically say “reform” … for that to happen.




  • Some further flavor to reinforce this: as I understand it, abortion is legal in the Netherlands until the fetus is viable, which was estimated to be 24 weeks but due to better care for premies IIUC it’s moving toward 22. After this time it is only legal in the case of serious medical problems: eg a risk to the life of the would-be mother, or because the fetus isn’t viable due to a defect. Until this year there was also a 5-day waiting period for abortions; I think that’s no longer legally mandated but the doctor still has input. I believe they also require more medical scrutiny after the first trimester.

    IMHO these are common-sense restrictions, though you could argue about the exact details. Abortion is accessible if you need it, but after a certain point a fetus is close enough to a person that its interests must also be taken into account.

    The official abortion rate in NL is slightly over 1/3 of that in the US. It may or may not actually be the lowest in the world: it’s hard to collect statistics in some places, especially where abortion is discouraged or illegal, or even in places where you would get one with no medical supervision (by pills taken at home).

    The Netherlands also has a low maternal mortality rate, around 1/5th of the US, and also one of the lowest in the world (says CIA world factbook), though I’m not sure how consistent these measurements are across countries.

    The US could achieve these things too, and likely have a lower abortion rate than it can achieve even through draconian restrictions. But it would require proper education and medical care, and that’s not what certain states want… they want the crueler option.
