<p>People do know on some level though. There was enough willpower to get the cookie bullshit on every website.<p>I think it's just that it's more of a visceral lizard-brain thing than a logical thing. Like how you can go through life eating meat every day, then someone sits you down and tells you the horrors of that industry and shows you a cow being butchered, and you go oh that's horrible, and then most likely put it out of mind and continue eating meat.</p>

<p>I think there's a very interesting duality forming around privacy. It seems like most people don't really care if they're being filmed, or if their data is being slurped up six ways from Sunday, as long as it's aggregated and going through automated systems. But as soon as it feels like an actual person is looking at individual behavior, it's creepy (which is, of course, always a possibility, but plausible deniability is a powerful thing).</p>

<p>I disagree, I found the story to be the interesting part. It's inspiring to me when people have the moral conviction to put themselves out there in a big way at great risk to their personal lives and mental health. And it was gratifying that he succeeded in swaying someone from the dark to the light.<p>History is rife with examples of "what's old is new again." Human nature and our psychological and social issues are basically constant throughout history. Good examples like this are always worth noting but, as you note, it's nothing very new, I'm sure one of the Greeks said something similar.</p>

<p>In another comment I recalled reading a paper while implementing Rayleigh and Mie scattering a while back...this was definitely it!<p>Getting it working was a "holy shit, we can actually model this complex real-world phenomenon pretty well with a few relatively simple calculations" moment. I went from a static blue skybox to a full day-night cycle just like that.</p>

<p>I implemented Rayleigh and Mie scattering for a game engine once (my own, hobbyist thing). It was pretty crazy to see a quite good sunset/sunrise cycle from those alone. IIRC even the sun itself popped out of that somehow.<p>I was using XNA (Microsoft's C# gamedev platform) and following Riemer's excellent series of tutorials, which have been preserved here[0], but I don't see anything about scattering. I might have gotten that bit from somewhere else. I do recall reading papers with math equations.<p>[0] <a href="https://github.com/SimonDarksideJ/XNAGameStudio/wiki/RiemersArchiveOverview" rel="nofollow">https://github.com/SimonDarksideJ/XNAGameStudio/wiki/Riemers...</a></p>

<p>I'm not really trying to white knight for academia. I know there is a lot of low-quality stuff (part of that is just reality, most of the work done in academia <i>or</i> industry won't stand the test of time). But I do kind of have to assume that if this field of work is continuing there is a reason and they haven't just been spinning wheels for 40 years because they missed something simple and obvious.<p>This article[0] says "Data changes are usually much less frequent than queries, so incurring an initial cost of processing data into an index is a fair price to pay for instant searches afterwards."<p>Is that what you're referring to with cache replacement? There's no way to quickly update the index?<p>Wikipedia says "The R-tree was proposed by Antonin Guttman in 1984 and has found significant use in both theoretical and applied contexts."<p>I'm gathering that there are applications which are ok with that limitation? Generally there is communication and awareness between industry and academia, if everyone really needs cache replacement for it to be useful, why have they not attempted to account for it? What is the cause of the total disconnect you describe?<p>[0] <a href="https://blog.mapbox.com/a-dive-into-spatial-search-algorithms-ebd0c5e39d2a" rel="nofollow">https://blog.mapbox.com/a-dive-into-spatial-search-algorithm...</a></p>

<p>I think it just goes back to what your goals are. I don't know for sure but I imagine the research you're describing as disappointing was never meant to be directly applicable to a real world problem. It's meant to explore and push the boundaries of our understanding in an idealized and theoretical sense. Over time the research that turned out to be important gets codified into textbooks and undergraduate courses and software packages, but if you're at the bleeding edge yeah it's gonna be tough to make sense of the landscape and apply it to your needs, but that's why people that can do it get the big bucks.<p>I mentioned nuclear physics because it's a wonderful union of theory and practice. The experimenters need theories to test, and the theorists need their ideas tested.<p>Contemporary AI is massively driven by research. There are a handful of influential papers from the past few years that have gone right into practice. Industry players have famously invested in their own academic divisions.</p>

<p>Another thought is that, I might be more likely to apply the term "ocean of uselessness" to a lot of what goes on in industry than to what academics are striving for.<p>People like having a job and a paycheck and accomplishing units of utility. But kludging together some libraries and maintaining another CRUD app isn't all that important or interesting in the grand scheme of things. The Von Neumann architecture and asymptotic analysis are, though.</p>

<p>But what is the teacher teaching from? Generally they are working off seminal and highly-regarded texts that the autodidact set would tell you to read anyway.<p>I will grant you that the current form of the education system, especially in light of how easy it is to engage with the primary resources nowadays, is massively inefficient and needs an overhaul to provide more individualized learning. Something like Alpha School is promising in this regard. But don't throw the baby out with the bathwater. Even if a kid today learns entirely "on their own" with an AI teacher...neither them nor the AI accumulated that knowledge, and we still need that infrastructure of people contributing to advancing and refining the shared knowledge base.</p>

<p>One thing I think a lot of people don't internalize is that academia and industry have fundamentally different goals. When I went into industry, I had the thought, like many others, that "my degree didn't prepare me at all for working with a production database, and I'm never gonna implement a Turing machine, wtf?" I think it was a major disservice to academia when college became seen as the path to a good job, because it was never meant to be that.<p>Academia is about pure learning about the world in a very deep and philosophical sense. It's about underpinnings and history and giving you the abstract tools to reason about things. Academics are often aggressively against learning practical things to solve a specific business problem. Which is what industry is all about. I think it's easy to take a degree program for granted, but it's difficult to understand how your brain would be different had you not done it (assuming one did apply themself and attempt to get its value. If you just cursed it the whole time yeah it probably was a waste.)</p>

<p>Again I think this is a false dichotomy. Learning "everything ourselves" does not mean going out literally by yourself and rediscovering everything from first principles. Whether you learned it from a dreaded teacher or from a manual or reference or tutorial or a more senior engineer, you're leaning heavily on the accumulated body of knowledge and "thinkism" that produced that.<p>You will learn some things through trial and error entirely on your own of course, but you will also take a lot of time independently re-learning things that are well known. Which isn't necessarily a bad thing. I'm a huge DIYer. Sometimes you have to try and see for yourself. But I do acknowledge that I could have learned a lot faster about, e.g., carpentry, as an apprentice, than I did mucking about in my backyard with youtube videos. I think the concept of "balance" is more important than taking sides on this matter. They're both incredibly useful tools to be used in conjunction. Read the manual. Then go muck around. Then read the manual again and go, "oh now I get what they were talking about."<p>I think what I'm learning from this is that a lot of the "entirely self-taught" folks don't realize how much they've benefited from "thinkism" and standing on the shoulders of giants.</p>

<p><i>You have your designs and then you open up a building to do repairs or start construction and some surprise presents you that you weren’t expecting.</i><p>And yet, the field of architecture is still highly valuable. Without those designs, there would be a lot more problems. Try building something complex without a design. You're going to waste a lot of time and materials. My point there was that it's not like the digital world where mistakes and trial and error and rethinking things can sometimes cost almost nothing.<p><i>Theoretical design is pretty worthless until you try it out. Until then it’s just an idea or hunch you have....ignoring all the years of trial and error that built a base of experience already</i><p>Lots of (smart) people have tried lots of things, there is a ton to learn from that, you're calling it worthless and taking it as an assumption at the same time.</p>

<p>I found the whole article to be a bit heavy on anti-academia. And I went to industry after undergrad.<p>It's a false dichotomy between the "thinkism" bogeyman (actually reading books and papers and putting work into theoretical design is just bad now? Have they tried building anything in the physical world? Checked in with nuclear physics, ever?) and hands-on experience. Both are important. It should be about balance, not trashing an incredibly valuable set of tools because others exist...</p>

<p>This is pretty much true, but also, you're older now. The people the age you are now were saying things like this when you were having all that fun. You are in a different place now. Your life is not about coming home after school and goofing off. You have <i>important things to do</i>. Those bored, lonely, funny, obsessive, angry, horny, curious kids are still out there, finding their version of what we had. They always are.<p>The internet may have changed, but the human spirit hasn't.</p>
