<p><i>> It's possible that the villagers were suspicious of Luria. It's also possible that the collective farm workers were suspicious of Luria. Don't you think it's possible for both of those to be true?</i><p>Sure. But that doesn't mean that "suspicion" always has to lead to the same behavior. "Suspicion" doesn't exist in a vacuum. You have to look at all the factors involved.<p><i>> The question is, what explained the difference in behavior of the two groups with regard to Luria's questions?</i><p>And the answer is, there were multiple factors involved, and trying to pin it down to just one is a fool's errand.<p><i>> Are you claiming that they knew the answer to the question yet refused to say it?</i><p>No, I'm saying that Luria's claim that the <i>only</i> reason they gave the response to the question was a cognitive difference between them and the collective farm workers who had been taught to read, is way too simplistic. And more generally, that Luria <i>only</i> looking at that one aspect of the situation--the possible cognitive effects of illiterate vs. literate--and ignoring all other salient differences between the two groups--like the fact that the villagers hadn't yet been forced into collective farm work by the Soviet government, while the farm workers had--is way too simplistic.</p>

<p><i>> These were previously peasants still under feudal lords.</i><p>What feudal lords? From the article's description it seems like they were basically on their own before the Soviet Union came in.<p><i>> Before somebody came to teach them under the communists, nobody cared if they were educated, or whether they lived or died.</i><p>And you think the communists taught the peasants to read for the benefit of the peasants? It is to laugh.<p><i>> This neo-John Bircherism masquerading as argument will always ignore the millions victims of tyrannical royals, or capitalist oligarchs</i><p>I'm not ignoring them at all. Where did I say that it was perfectly okay for tyrannical royals or capitalist oligarchs to kill people?<p>Indeed, if you look at how societies under tyrannical royals or capitalist oligarchs are run, they basically have the same problem I described: one person, or a small elite, at the top thinks they know enough to run an entire society. But they don't. And their attempts to do it cause massive human suffering and death.</p>

<p><i>> The correct thing to do if someone asks you a question with obviously false premises is to push back!</i><p>More generally, Luria completely ignores a key psychological dynamic that's in play as he tries to quiz these villagers: they're going to be suspicious of why he's even doing all this in the first place. What is he up to? And of course he <i>was</i> up to something: he was a agent of a horribly oppressive government that was trying to totally change the villagers' lives.<p>That kind of intellectually dominated "democracy" <i>killed well over a hundred million people in the 20th century</i>. And the people who promoted the horribly oppressive governments that did it--the Soviet Union, Mao's People's Republic of China, the Khmer Rouge in Cambodia, etc.--were among the most intellectually sophisticated and literate people on the planet.<p>None of this is to say that illiteracy and ignorance are good things. They're not. I'm much better off in my personal life being literate and knowledgeable. But literacy and knowledge have limits, and the people who want to dictate how entire societies should be organized and run based on their literacy and knowledge are in over their heads. Basic human instincts and intuitions, like the ones those villagers had that Luria completely missed, contain valuable information too.</p>

<p><i>> the gif you saw makes it look that way.</i><p>Makes it look what way?<p>Watch the NASA video carefully. It's clear that, even before the "loop" begins, Artemis is slowed down and is soon going to reverse direction relative to Earth. Which of course it would anyway, as you say--because, as the video you linked to points out, it doesn't have Earth escape velocity. The TLI burn gave it just enough velocity to reach the Moon's orbit with a little extra speed left over to get it about 4000 miles further.<p>But what would <i>not</i> happen without the Moon there is the "backwards" part of the loop--the part that took Artemis around the far side of the Moon. The Moon's gravity is what did that. In the Moon-centered frame in the video, yes, it looks like just a slight deflection--because that frame is moving with the Moon, whereas Artemis was moving <i>backwards</i>--in the opposite direction from the Moon in the Earth-centered frame.<p>Without the Moon there, Artemis <i>would never have moved backwards, relative to the Moon's orbit, at all</i>. Its trajectory in the Earth centered frame would have been a simple ellipse, with a maximum altitude from Earth a little higher than what it actually achieved (since the Moon's gravity did pull it back a little bit).</p>

<p>My father, who flew combat missions for the Navy in Vietnam and then became a test pilot, told me after the loss of Columbia that if he had had a chance to make that flight and spend 7 days in Earth orbit, even knowing that he'd burn up on reentry, he'd have done it.</p>

To ask the question in the title and then not argue for an answer in the article is a cop-out. It's trying to have it both ways.<p>An article that was simply going to report what was found factually, with no editorialization, would be better done with a title something like "Sam Altman: A look at the career of a key person in AI".</p>

<p><i>> the article should just present information, ideally in a balanced way, without author's bias, so that you can decide for yourself.</i><p>I get that this is the claimed ideal of journalism, at least for straight reporting. The problem is that it's impossible.<p>There isn't time or space to present <i>all</i> the information; the journalist has to filter. And filtering is never unbiased. Even the attempt to be "balanced" is a bias--see next item.<p>"Balanced" always seems to mean "give equal time and space to each side". But what if the two sides really are unbalanced? What if there's a huge pile of information pointing one way, and a few items that might point the other way if you believe them--and then the journalist insists on only showing you a few items from the first pile, so that the presentation is "balanced"? You never actually get a real picture of the facts.<p>There's a story that I first encountered in one of Douglas Hofstadter's books, about two kids fighting over a piece of cake: Kid A wants all of it for himself, Kid B wants to split it equally. An adult comes along and says, "Why don't you compromise? Kid A gets three-quarters and Kid B gets one-quarter." To me, the author of this article comes off like that adult.<p>In any case, all that assumes that this article is supposed to be just straight reporting, no opinion. For which, see the next item.<p><i>> It can be debated whether the title should be such a question.</i><p>Yes, it certainly can. If this article is just supposed to be straight reporting--no editorializing--then that title is definitely out of place. That title is an editorial--and the article either needs to own that and state the conclusion it's trying to argue for, or it shouldn't have had that title in the first place.</p>

<p>Because their strategy for getting their applications in front of everyone has always been to get Windows in front of everyone, and that meant having to support third party applications that they chose not to try to incorporate into their own apps, but which got enough usage that not supporting them would mean losing those Windows desktops, and thus losing those users of the MS applications that were on every Windows desktop.<p>It's quite possible that this attributes too much intentional strategy to MS, and also treats them as a single entity with a single strategy more than they deserve. The MS internal teams that were bending over backwards to maintain backwards compatibility were not the same as the teams that were churning out new APIs, building Azure, etc., and quite likely had very different incentives.</p>
