<p>As engineers we know that you can't catch everything. You build resilient systems by learning from your failures and investing/iterating in better practices over time. If you want to find out how to sabotage your company really quickly, just throw a bunch of politically radicalized interns with stupid red hats at your testing, QA, dev/ops, security, customer success (+etc) procedures, slash budgets, randomly, delete test suites and see where you land. Then when things go wrong, make sure your defense is "well we don't know they would have caught anything anyway."<p>The cuts were actual. There's no sense in calling something that is a matter of open public record which has been widely reported on "alleged."<p>I understand MAGA types like to fall over themselves to evade responsibility for their actions, because they think truth is a shell game and reality has no meaningful consequences if you deny them loudly enough (see: deaths due to science denialism during the covid response and shilling of bro-science alternative medicine, upsurge in preventable illnesses like measles due to vaccine denialism, brain drain from the insane gutting of public research funding institutions and cynical re-alignment of said institutions around corporations that donated to the presidency, drastic consequences of global warming, consequences of 2A zealotry in the form of school and other mass shootings... and so on and so forth).<p>The hard reality is that we've been trying to get a handle on food safety for over a century. It is incredibly laborious, difficult work that requires knowledge of the many and various ways contaminants make it into the food supply, how food producers like Taylor Farms obfuscate or lie to avoid legal liability or costly regulation, and knowledge of the law and how to shape and administer it effectively. If you slash regulatory agencies that have emerged over decades to own and shepherd this work,  you're going to have to own up to a lot of nasty shit over the next few decades.<p>In my state, water pollution was so bad in the 70s and 80s you couldn't swim in major lakes and streams. Now you can. We got there through sustained public investment in regulation and oversight. We need more of that, not less.</p>

<p>It is falsifiable, in the sense that we have ample evidence of the many forms of life that have existed on earth... including fossil evidence, genetic evidence, preserved tissue samples and a long litany of other pieces of data broadly consilient with our understanding the biological timeline.<p>On the other hand, we have zero evidence of Silurians or whatever.<p>Those two observations are inconsistent and require explanation.<p>Sure, one can hedge and qualify and excuse or whatever, and on pain of irrationality we have to allow that it's <i>possible</i> we're missing evidence of one of a bajillion possible competing hypotheses about intelligent life... but the theory most consistent with the evidence we have is that there wasn't any.<p>That's falsifiable enough for me?<p>The criterion of falsifiability pushed by positivists is kind of crappy anyway, it doesn't speak well to how we build models of the world while doing actual empirical work (and is itself non-falsifiable), but in practical terms idk, I don't see much to recommend the Silurian Hypothesis over the null hypothesis, so to speak.</p>

<p>The history of mathematics is tightly coupled to spirituality... some more famous examples off the top of my head are Cantor, Euclid, and Euler, but there are probably hundreds of examples of folks who explicitly tied their faith to their research.<p>I definitely don't think there's anything inconsistent with mathematical and theological thinking. That actually strikes me as a very strange idea?</p>

<p>The capital required to train Qwen at scale is enormous. The capital required to patch a linux distro is near zero. Any scale model coming out of China should be viewed as advancing a geopolitical agenda. The same skepticism should be applied to any model trained in the states, but that should be viewed through the lens of short-term business profits.<p>There are earnest nerds everywhere, in every society. No doubt. But "Chinese AI Labs" operate at the whim of the Chinese government, in the same way "American AI Labs" operate at the whim of billionaire investors. Inferring good will from either is naive at best at this scale.</p>

<p>Refusal to consider evidence to the contrary is certainly symptomatic of something, and it isn't a well-reasoned argument. "Us" sounds like the corporate leadership I work with that have actively pushed teams to incur mountains to tech debt. I was walking over org metrics this week and sure enough, there's a rising tide of unplanned work for bugs, performance problems, and security snafus introduced during an aggressive push into GenAI with pressure to "just make agents do it."<p>All of which was, of course, predicted by management, reported upwards, and ignored.</p>

<p>That right there is the mentality that is going to drive me into a hole. Engineers are already grumpy enough dealing with asinine human bullshit that doesn't translate into reality. Seeing blatant slop judged by blatant slop (and it is, in this case, extremely blatant on both ends) and then saying "geez if you're criticising this you must be butt-hurt, move on" is so <i>mind-blowingly</i> frustrating. Like you can't even start to reason with someone like that. Yes, the author of the comments clearly believes other submissions made sense and engaged in good faith with the competition parameters, and that those deserve to win. Are we stupid?<p>We tried! In good faith! We put a lot of time into articulating ourselves clearly! We even pretended to be nice, reminding ourselves to be charitable and that we might be missing something! And like... it's normal every once in awhile for someone to opine dumbly, but when it's all the time and the perpetrators are people who just do not care that they are spewing glorified Bayes-slop into the universe and then being rewarded for it by people who both can't tell the difference and don't understand why that's a problem... we all get really tired, really quickly, and we want to disengage.<p>Personally I have zero tolerance for this kind of lazy-ass approach to reality. I'm seeing it increasingly at work. I'm seeing it increasingly in corpo sludge. I'm seeing it increasingly in social interactions. I'm seeing it explode on social media. I want to engage in life-affirming activities with people who have actual minds that they cultivate and use. I will not waste precious time and attention on communities that tolerate slop. If you want me to care, communicate with me in good faith. I don't think we should be kind or forgiving about it. Kaggle got exactly one strike on this, now they're dead to me forever. Same with open source contributors. Same with content creators. Out of basic ethics I need to give multiple strikes to employees who report to me (and hold myself accountable for their actions first), but exactly one strike for leadership above. Trust is precious. We need to hold one another accountable. If that burns some bridges so be it. Enough is enough and we do in fact know better.</p>

<p>Having learned math in an accelerated program that banned calculators, my experience has been that they do substantially diminish mathematical learning. They are useful for things like building an intuition about the behavior of functions... but ask a student to manually graph and compare  the behavior of some fairly trivial functions ( ln x, 1/x, sqrt x, x^3 ) over the interval [0, 1] and you'll pretty quickly see the difference between kids who are trained to think for themselves and kids who aren't.<p>The ability to engage with math "critically" is fundamental to being able to use it constructively/creatively.<p>I think we're seeing the impact of LLMs more broadly in the drastic decline in incoming freshman academic competency levels, and will continue to observe people becoming measurably, meaningfully stupider until we clamp down on / outright ban LLM usage in education.</p>

<p>Note that every single person telling you to not learn to code currently knows how to code, often at an expert level, and is therefore capable of reasoning about code.<p>I learned to build such useless things as operating systems, databases and neural nets from scratch. That knowledge is foundational to my ability today to lead technical teams effectively, even in the era of copilot.<p>I would absolutely not hire an engineer who could not code. Don't get me wrong, I don't need code monkeys any more than I need assembly experts.<p>I need engineers who have experience building, tuning and maintaining complex software.<p>Someone who can't code can't crack open what they're working on and reason about it in a meaningful way. That's a huge liability. Also like... they just haven't ever done that work before. I don't even know if they're going to be capable of it.<p>I did some consulting a few years ago to convert startup codebases from Ruby on Rails to something that "would scale". Some of the projects I opened up were beyond comical. Millions and millions of dollars of investor capital burned torturing cut-rate junior engineers to get them to make a product-shaped solutions that could not be maintained, could not be scaled, could not be modified without everything breaking... entire teams of cheerful idiots who were replaceable with a single capable senior engineer who knew what they were actually doing. It was just tragic. Literal futures burned up as friction with reality, because neither the founder nor their engineers could write actual code to build clean, scalable systems without tripping over their own feet.<p>You're signing future engineers up to be those utterly lackluster juniors for the rest of their lives. Stay in school kids. Learn to code.</p>

<p>Ease off the adderall bud.<p>There's a lot of sloppy thinking in that post, starting with the pseudo-scientific framing in terms of evolutionary psychology... which is ironic given then ScIeNcE-bro tone... couched against an artificial and incorrect taxonomy of reason into "philosophical, logical and scientific"... in reality those are intersecting at times, orthogonal at others, and the devil is generally in the details... but it certainly doesn't make sense to impose some kind of juvenile "batman vs superman" power scaling hierarchy on top of them...<p>The reduction of the results of an argument to a binary win/loss between two people is probably the most humorously absurd bit. There are many outcomes of an argument. Sometimes it pivots research in a fruitful direction. Sometimes it leads to compromise. Sometimes parties talk past one another. Sometimes it serves to create an artifact for later analysis/reflection. Sometimes it causes us to pause and re-evaluate before acting. Sometimes it plants a seed that bears fruit later. Sometimes it strengthens both parties by refining their respective views. Sometimes it wastes everyone's time and nothing valuable comes of it.<p>Pursuit of knowledge or aligning action to truth isn't an arm-wrestling contest with winner-takes-all outcomes. That's just a silly framing that doesn't reflect reality, it's the kind of way you see the world of you aren't actually part of knowledge production and consume "debates" as influencer-slop from Ben Shapiro types.<p>I argue with people all the time. At work, with friends. It's generally a form of productive commerce. I see things one way and have knowledge/strengths that I bring to bear through my perspective. Others have their own knowledge/strengths. Working together, we might build a scalable data system, prioritize a road map, design a better game, make food decisions at a restaurant, have an enlightening political conversation, improve a speedrun. Whatever, the ends are various. The means are often spirited debate, in which, generally, everybody wins. That's just kind of the first principal of macro economic theory, if you need a bro-system to cash things out into.</p>
