<p>There's a simple energy argument for both predation and war. It is energetically cheaper to take than to build. If you can take with low risk, there is no (energetic) reason to not do so.<p>Collaboration is the exception. That collaboration is everywhere in many forms is a testament to the power of natural selection.</p>

<p>Agree. Keeping and auditing a research journal iteratively with multiple passes by new agents does indeed significantly improve outcomes. Another helpful thing is to switch roles good cop bad cop style. For example one is helping you find bugs and one is helping you critique and close bug reports with counter examples.</p>

<p>Think about it this way - if Russia had the US Navy's task force near Ukraine, and the level of air dominance that US has in Iran, do you think Russia would do anything differently? Would they, for example, be making 100s - 1000s of daily aerial strikes anywhere in Ukraine?<p>Because US _does_ have that, and so it _does_ significantly change the calculus. Unless you think it doesn't. In which case, we just disagree.</p>

<p>This is a fairly well trod argument. It also requires a fairly long series of strawman arguments to come together. Yes, there are challenges, but ...<p>The reality of Hormuz was well known decades ago - even in 2002 Millenium exercise a bunch of speedboats and motorcycles stopped the US Navy from opening hormuz. [1]<p>Moskva was taken down by a well coordinated strike that distracted its one (1!) fire control radar. It was also alone. Those are important factors. [2]<p>A blanket comparison of Russia's attempts to eliminate Ukraine's industry with US Navy's ability to eliminate Iran's is ... questionable. We've flown 1000s of uncontested sorties over Ukraine, and Russia has been relegated to knocking down apartment buildings with Iran's own drones.<p>It is entirely possible that the US Navy is commanded by myopic idiots who fall for those tricks, but I doubt it.<p>Finally, it's not entirely clear that the large population won't, itself, become at least partially an asset of the resistance.<p>[1]: <a href="https://en.wikipedia.org/wiki/Millennium_Challenge_2002" rel="nofollow">https://en.wikipedia.org/wiki/Millennium_Challenge_2002</a><p>[2]: <a href="https://www.forbes.com/sites/davidhambling/2022/04/14/ukraines-bayraktar-drones-helped-destroy-russian-flagship/" rel="nofollow">https://www.forbes.com/sites/davidhambling/2022/04/14/ukrain...</a></p>

<p>Please ask yourself if there is true evil in the world. People who are willing to kill children <i>on purpose</i>, or maim them, or burn them with acid, or commit other bad things I wont get into.<p>Then ask yourself if bad things can happen despite good intents. Truly horrible things, in fact, despite effort to prevent them.<p>Then, ask if this bombing was part of group A or group B.<p>And ask if we were <i>trying</i> to target people from group A or group B.<p>This is not an "ends justify the means" argument, I hope. But if <i>you</i> want to count bodies as some kind of justification for or against war because apparently morals can be reduced to addition and subtraction, you might as well at least classify the dead and causes correctly.</p>

<p>I will try to respond to all these independent threads, but we can't continue all of them at once.<p>> . “These aren’t just nameless, faceless targets,” he said later. “This is a place where people are going to feel ramifications for a long time.” The targeting cycle had been fast enough to hit 50 buildings and too fast to discover it was hitting the wrong ones.<p>> The air force’s own targeting guide, in effect during the Iraq war, said this was never supposed to happen. Published in 1998, it described the six functions of targeting as “intertwined”, with the targeteer moving “back” to refine objectives and “forward” to assess feasibility. “The best analysis,” the manual stated, “is reasoned thought with facts and conclusions, not a checklist.”<p>> A former senior government official asked the obvious question: “The building was on a target list for years. Yet this was missed, and the question is how.”<p>---<p>> Please reason through the implications now?<p>It was a mistake. My girls are about to enter this level of school, as well (cool parent card). A mistake/error/tragedy can all accurately be used to describe this. It's horrible it happened. All I'm saying is that no process is perfect. It is not excusable, but it is unfortunately understandable how it happened in this situation.<p>> 1000s<p>1000s is fairly easily understood. 1/1000 is inferred b/c as you say, "public pressure" sprang up immediately after this one bombing. Iran regularly posts pictures and videos online, and human rights orgs are clamoring to find evidence. Either we are <i>really good at suppressing the world except for this one case</i> or there aren't that many schools being bombed. We cannot be simultaneously horrible at picking targets and suppressing evidence and also great at it in every other case. Planet labs themselves provided the pictures - they are freely available.<p>Yes maybe the machine lumbers on, stomping on kids, or maybe we've learned our lesson and are now perfect, but this <i>seems</i> like the kind of mistake that can happen, and it <i>seems likely</i> that the analysts involved here are now benched and I wouldn't be surprised if <i>some</i> corrections are happening internally. These are human beings, despite what the article would have you believe, that are doing the best they can.<p>> we targeted and killed young children<p>We killed young kids, but not on purpose. We targeted a building and intent matters. I refuse to believe anyone in the decision chain would move forward if they believed kids were going to be killed. If you do - how can you? Why would they?<p>We're going to quickly get into hypotheticals here. There's a lot of open threads, and believe me I hate with the fullest extent of the word violence against children. We can leave it at that.</p>

<p>I recommend looking closely at the New York Times analysis. There were factors that might have mitigated this as a strike target, but it also really did look like a part of the compound (and it originally was!). Yes, with hindsight, we can definitively know, and with sufficient time each target could probably have been positively ID'd, but there was precisely one mis-strike in 1000s of sorties, so this already is a low error rate. TFA discusses 50 specific strikes all of which missed via automated analysis. That doesn't seem the same.<p>I don't disagree there. But this is not a case of hallucination, and an existing website is a signal, not a determinant, of the real situation on the ground. 
However, you have made a very, very strong assumption that these targets were not carefully evaluated. One that does not seem to be present in TFA or any analysis that I've read. In fact, the article itself quotes those in the know who <i>believe this should have been eliminated as a target</i>.</p>

<p>No, what I said is not wrong just because there exists other things to intercept, that just changes the ratio.<p>You still have to consider whether it's worth it to spend a patriot missile to intercept a drone, vs letting the drone hit, say, a billion dollar radar installation or a dozen troops.<p>On the manufacturing side, nobody said that all drones are intercepted with patriots. You have to look at the avg cost to intercept vs the average cost to attack, and if the ratio of those avg costs (across all attack/interceptions) is, say 100:1, and the combined GDP of the defending nations vs Iran is 1000:1, then what is the problem?<p>There are lower cost ways to intercept already on the market and being rolled out. See for example: <a href="https://www.defensenews.com/global/europe/2025/09/11/uk-to-produce-ukraine-designed-interceptor-drones-supply-thousands/" rel="nofollow">https://www.defensenews.com/global/europe/2025/09/11/uk-to-p...</a><p>This whole "cost analysis of patriot vs drone" examines the worst case scenario at a fixed point in time and ignores layered defenses, the effect of combined GDP, learning, diminishing capabilities of attackers, and improvements by defenders.</p>

<p>Ah yes, but then you also have to add GDP + targetting/defense radii.<p>Great Britian alone has 10x the GDP of Iran. So an interceptor costing 10:1 is (at first approx) breakeven just for GB, who would have to intercept much less than the total manufacturing capability of Iran anyway.<p>Then you have every rich nation surrounding Iran as well. Let alone the USA who cannot be reached but throws their weight behind interceptions.<p>And finally "total manufacturing capability" is set to decline in any prolonged engagement with an Iran-like nation, but GB, western EU, USA, et al, are likely to only increase production if an engagement played out.<p>The math looks catastrophic on paper at 10:1, but I sincerely doubt that's the right analysis. An interceptor is worth what you're protecting, not what the attacking asset costs, so long as you can keep producing them.</p>

<p>Quite a decent read, actually.<p>Boils down to the same "Typing is removed as a bottleneck but it was never the <i>real</i> job."  And at least attempts to re-instill a lost sense of agency I see from developers here and there.<p>Essentially.. "The craft changes, you decide to maintain what you love or what the market rewards". So, maybe we all just loved coding <i>so much</i> that we happened to make money doing it? I'm not sure that's the essence of the anxiety floating around. I think it's more of an evaporating opportunity to use your experience to provide for yourself, that people are worried about.</p>
