<p>I don't think that complaining about things necessitates believing that you're entitled to them. I agree that complaining about things you received for free is in rather poor taste, but I don't think that it's morally wrong in the way that you seem to think it is. If an article you read for free had a pop-up ad on it, you have not been wronged in any way and do not have grounds to sue them, but you should be permitted to voice your complaint, so long as it's of the form "I don't like this" and not "look what they subjected me to, those monsters".</p>

<p>The Copilot in Visual Studio (Code) is not the same as Microsoft's Copilot. The former is GitHub's AI product and the latter is Microsoft's AI product. You can tell them apart because GitHub Copilot's icon is a helmet with goggles and Microsoft Copilot's icon is a colourful swirl thing.<p>It's wildly confusing branding not only because they're identically-named things that both repackage OpenAI's LLMs, but also because they're both ultimately owned by the same company.<p>I can only assume that the conflicting naming convention was either due to sheer incompetence or because they decided that confusing users was advantageous to them.</p>

<p>There are other substances that can be used for reactor coolant. Molten salt reactors are  actually substantially more efficient than water-cooled reactors because they have a higher operating temperature. You can also use liquid metal as coolant, such as lead or bismuth.</p>

<p>Could you elaborate? Why would being deep in the gravity well be a non-starter? I thought Mercury's proximity to Sol was a huge advantage because of the ample solar power which would make planet-side manufacturing easier.</p>

<p>They asked if the astronauts "want to risk it", not if it was actually safe. Those are very different questions. The astronauts are, in fact, the world's leading experts on whether or not they personally want to risk it, so it's not entirely unreasonable to think that they could answer that question.<p>It just depends on whether you think that the fact that they accept the risks is reason enough to let them fly a potentially-dangerous spacecraft.</p>

<p>The semantics that make sense to me is that "DDoS" describes the symptom/effect irrespective of intent, and "DDoS attack" describes the malicious crime. But the terms are frequently used interchangeably.</p>

<p>Firstly, since this argument is about semantic pedantry anyways, it's just denial-of-service, not distributed denial-of-service. AI scraper requests come from centralized servers, not a botnet.<p>Secondly, denial-of-service implies intentionality and malice that I don't think is present from AI scrapers. They cause huge problems, but only as a negligent byproduct of other goals. I think that the tragedy of the commons framing is more accurate.<p>EDIT: my first point was arguably incorrect because some scrapers do use decentralized infrastructure and my second point was clearly incorrect because "denial-of-service" describes the effect, not the intention. I retract both points and apologize.</p>

<p>Unintentional denial-of-service attacks from AI scrapers are definitely a problem, I just don't know if "theft" is the right way to classify them. They shouldn't get lumped in with intellectual property concerns, which are a different matter. AI scrapers are a tragedy of the commons problem kind of like Kessler syndrome: a few bad actors can ruin low Earth orbit for everyone via space pollution, which is definitely a problem, but saying that they "stole" LEO from humanity doesn't feel like the right terminology. Maybe the problem with AI scrapers could be better described as "bandwidth pollution" or "network overfishing" or something.</p>

<p>In a similar vein, I want a text editor where pasting from an external source isn't allowed. If you try, it should instantly remove the pasted text. Copy-pasting from inside the document would still be allowed (it could detect this by keeping track of every string in the document that has been selected by the cursor and allowing pastes that match one of those strings).<p>It wouldn't work in every use case (what if you need to include a verbatim quote and don't want to make typos by manually typing it?), but it'd be useful when everything in the document should be <i>your</i> words and you want to remove the temptation to use LLMs.</p>

<p>Which is especially odd because the author (Sam Hughes) lives in the UK and wrote the original in UK English, but apparently wrote the rewrite in US English. For example, a chapter in the original was titled "Case Colourless Green", but in the US edition of the rewrite that chapter is "Case Colorless Green" (without the 'u'). So Hughes, a native UK English speaker, wrote the rewrite in a non-native (to him) dialect, then had it (lazily) translated into his native dialect.</p>

<p>> The only way text can become communication is when the writer has intents<p>I'm curious as to what you mean by this. I assume you don't mean it literally, as that would be trivially falsifiable (for example, the text readout on a digital caliper doesn't have "intents", yet it absolutely communicates meaning), but I can't think of another way that you might have meant it. Could you elaborate?</p>

<p>Counterpoint: a major use case for this technology would be to experiment on human brain structures to research and hopefully cure neurological diseases like Alzheimer's. If you want to cure Alzheimer's in humans, you might as well use human brain cells from the start.<p>But yes, I agree that they're likely using human brain cells mainly because it's attention-getting.</p>

<p>Is there a reason they're using human brain cells specifically? This seems like it would also work with neurons from other creatures.<p>I was under the impression that the relative intelligence of humans versus other animals was largely a function of brain cell quantity, not quality. Can 200k human brain cells really learn faster than 200k mouse brain cells?<p>A more cynical take is that they're just using human brain cells for shock value. They chose DOOM because of the "can it run DOOM" meme, so they clearly value publicity a lot.</p>

<p>> Here's the thing, people make casual remarks, they use imprecise non technical colloquillisms.<p>I think that you're completely misunderstanding my objection here. I'm not in the least bit upset by people using "zip" casually to mean something other than formal ZIP files. I personally use "zip" as a verb to describe compressing to a tarball, for example. This is a technically incorrect usage, but it's okay for things not to be absolutely technically correct.<p>My objection is to \3, both to your summary of it and to the actual message content. godelski did <i>not</i> "indicate that they had used zip colloquially"; they accused sweetjuly (who fully understood that godelski was using the term colloquially and was simply making a humorous, playful, and lighthearted correction that didn't warrant further reply) of hyperfixating on the colloquial usage of zip. This is not only technically wrong (sweetjuly was "hyperfixated" on the technical definition, not the colloquial usage), but it's also accusatory and mean-spirited.<p>> Do you believe it served a useful purpose to double down and restate something that was very likely well known to both parties over a week ago?<p>Not in a strictly pragmatic sense, no. I intended to set the record straight by clarifying the factually accurate statement that ZIP is not a lossy format, which seemed to be contested. I didn't expect anybody to read my comment to an 8-day-old threat, nor did I expect anyone to reply to it barely 3 minutes later, nor did I expect to be drawn into a 7-reply-long debate about this.<p>Isn't it delightful how well we've proved godelski's original point about how fraught natural language is?</p>
