<p>Indeed. At uni, starting in my second year, I worked as a programmer (no remote work, office at 1hr commute from uni dorm) on top of my studies. It was hard, but doable. My major was applied math, so the CS part was the easier bit, but the math, especially Analysis, Numerical Methods, Linear Algebra, and Analytic Geometry they kicked my butt. We also had a really bad prof for the Math Logic class and no textbook, only lecture notes and his lectures were unstructured shit :(<p>The biggest problem wasn't the workload itself, but how inefficient learning was back then. It was the early days of the Internet, no coursera, no Google indexed uni sites, no LLMs, no online tutors. I only had a mediocre textbook and some notes I borrowed from friends when I couldn't attend lectures or labs. It took ages. I’d burn hours trying to parse two paragraphs in the textbook, only to ask mates who didn't understand it either.<p>Now, we have an incredible amount of information & tech at our fingertips: LLMs, Google NotebookLM, online tutors, dozens of textbooks, and sites like Anna's Archive packed with high-quality "free" material. With all this technology, the time it takes to understand, prepare, and master a topic is a fraction of what it used to be. It still takes work and discipline, but man... you can feed textbooks into an LLM and use targeted prompts to debug your exact knowledge gaps on the practice test you get from the LLM.<p>So I reckon it's easier now than before, simply because learning can be done so much more efficiently. After all these years, I still remember the hardest classes and the most stringent professors with great affection - even though I hated those bastards back then. My Group Theory prof once invalidated a definition I wrote because of a single missing word. At the time, I thought it was an injustice, but later I realized that word was crucial.<p>University is where young people must face hard work and reality, because it teaches them what true meritocracy is. It should be hard, it's the same way a gym workout should be hard or it’s ineffective.</p>

<p>Yes, there are many misconceptions on "learning", but LLM can be useful.<p>The approach that works for me is using Justin's skycak methods he mentions in his books:<p><a href="https://www.justinmath.com/books/" rel="nofollow">https://www.justinmath.com/books/</a><p>Check the shorter "Advice on upskilling" or "The Math Academy way" for well researched approach.<p>So what works for me<p>- open a project in ChatGPT/Notebook LM
- dump all the relevant and highly cited materials (textbooks, papers)
- dump the advice on upskilling text or a short summary I've written for the LLM<p>- create "Learning Goals", that contain what I want to learn, and how to estimate is  my level good enough<p>1) Ask it to create a learning path from the materials, following the approach. Give that to an adversarial LLM for cross check. (just for sanity check)<p>2) Ask it to create an "entry test" to check what I do know and what I don't<p>3) Iterate step by step on each module/submodule from the learning path that intermingles the approach of: small theory step + small practical task + small test. Log what's missing/wrong in my dept log. Give the dept log at the end of the session to the LLM to incorporate/create another test/task.<p>What I have found useful in this approach is that it will generate a lot of practical tests/tasks for me and it will explain a concept in many ways until I understand it. Also it finds some prerequisites I might miss, but based on my tests and debt log unexpected things I thought I understood surface.<p>So with the limits of LLM and while building a mental map of the relevant parts it's usually enough to spot the hallucinations, but if you apply structured approaches these are minimal. And it's super good, because the number of practice tests and explanations is endless.<p>The interfaces are a bit clunky, but current multimodal LLMs are ok with images or even hand writing.<p>I will recommend that structured approach.</p>

<p>Yes, there was investment, but investment without free markets and capitalism doesn't work usually for end products like cars. It's not a linear function of the capital invested, it's not possible to spend your way into good consumer products. That's not infrastructure. That's why I was mentioning that before Tesla came that investment didn't lead to any strong EV automotive players. In 2016 there was a big scandal on widespread EV fraud, where manufacturers just built to get the subsidy(骗补).<p>The policy shift came around 2017 when the government understood that subsidies and closed market created lazy automakers (e.g. check the US market for the same dynamic in trucks). In 2018 they removed subsidies for cars less than 150km of range and changed the requirements to receive them tying them to battery density.<p>After Tesla came and subsidies were reduced, most of the inefficient companies went bankrupt. It was the free-market competition that killed them. The reason why it changes was the competition not the subsidy. The subsidy was somewhat important, but as many of us knows, nothing government run produces good consumer products, you need market and free choice to get productivity. So it was the free-market and subsidy cutting that created the BYD, Li Auto, Xpeng and Nio. That's the proof that without free market it's impossible to have strong companies. And without subsidies you can have strong companies, even if it takes more time.<p>In EU and USA subsidies didn't create a lot (Northvolt?), because there were not enough free-market driven demand and too much regulation to jumpstart the free-market forces that will start the engine of innovation.<p>So the answer is not "capitalism and free-market doesn't work and governmental industrial policy is the answer", but it's the market that creates the strong companies. You can speed it up with venture/government capital, but without the brutal competition in the marketplace where people vote with their wallets you won't make it work.</p>

<p>It was the market that delivered BYD and Xiaomi. The government did his part with industrial policy and inviting Tesla to China to help start the ecosystem, but the brutal competition between Chinese auto makers following the rules of capitalism and free-market made those who survive the ones that can compete with other global companies. Before that they just subsidised and all they got were regional "champions" that siphoned out the funds and created shitty products no one wanted.<p>After Tesla came with special laws allowing it to work without Chinese co-ownership, but with a mandate to source from Chinese suppliers, this created the ecosystem needed for the next iteration, by the capitalist urge of Elon to get into the market and by free-market economy of suppliers to Tesla that are up to the standards to supply it.<p>The government set up the battlefield, and let the free-maket filter the strongest to survive.<p>In the Western countries the government and regulations are frequently the bane of the car companies. Good luck opening a mine or a battery factory in Germany, regulation, unions, green mandates, 36 hr. week. You can't fight with 1 leg tied.</p>

<p>There is also another benefit to books, on average they are much better than a random 3 hour podcast. 
If you care about what you read, you'd be getting something that the author has spend a lot of time, skill and energy to write, the editor would have spend a lot of time and skill to improve with the author.<p>I have a measure for all content I consume, quality/hr of reading/listening. If it's just a long video that has 2-3 questions that has caught my attention I'd be listening only those. If it's a long text that I might find something interesting I'll ask the LLM to summarize the main ideas as a filter before I decide to dive in.<p>Books, and their audiobooks version have on average much more bang per hour than random podcasts, because they're structured, authors had spend more time on them and you can cherry pick from a structure.<p>I also have caught myself using sloppy content as excuse not working on planned tasks with excuses like "this might be useful", or watching "productivity porn" videos. I think LLMs are good as a pre-filter for that.</p>

<p>I got this problem with my own employees, LLM are fine, but lazy slop is not permitted. Current idea is to have a clear "best practice" template for most of the research/specs/problem definition they submit and it reduced the slop to a manageable level. 
But this might work in a smaller company where the management is reading and is strict about these things.</p>

<p>I have one IKEA Apstuga on my desk, sitting right next to a good CO2 monitor. 
Since Apstuga uses worse approach (heat) rather than light as the good sensors, it diviates around +/- 100 ppm. For example the correct CO2 is 610 ppm and IKEA's sensor shows 552 ppm with is reasonably close. So the trend will be correct and the values will not be.<p>But when it goes over the safe limit it should be enough to decide to ventilate.</p>

<p>It's strange how people search for cartels where the basic laws of supply and demand are at work. 
It seems to me, that such a simple concept should be better understood, especially in any market economy, where most of the people has sold something online and priced it somehow. 
But alas, that's not what's happening, is this because of the discourse of "if I don't like something it's because of some evil corporation tries to squeeze me"? (many examples of those, but not all markets are Apple Iphones)</p>

<p>I live in a house that is at least 110 years old, built around the time Australia became a federation. The house has been repainted and extended several times, but it still has 3.5-meter-high ceilings, ventilation holes with intricate metal bars, and a lot of original details.<p>Even though the house is really old, it has been taken care of. There is no mold, the doors are still the same original ones, the fireplaces with decorative tiles are still there, and the wooden fireplace parts are still in good condition. I don't know how they did it, but it was built rather well.<p>Interesting tidbit: on the ceiling there was something like a Star of David. After asking LLMs what it was, one of them said that when Australia became a country, the Federation Star had only six points, denoting the newly incorporated states, but later a seventh point was added. Gemini told me that the frieze details were typical for the 1901-1910 period, and this helped me date the house.<p>This took about 10 minutes. Before, it would probably have taken me at least several hours of Googling.</p>
