  1. Funnily enough, the future of the Chinese economy depends on being able to access their local market. The chinese people save too much and aren't buying their own products
  2. I don't think many equipment makers are Taiwanese. The names I am familiar with are KLA from the US. Tokyo Electron from Japan and ASML from Netherlands. TSMC buys equipment from them and build the fabs. The PRC wants complete vertical integration.
  3. Funnily enough, linear algebra is a good example of how doing doesn't lead to understanding. Just calculating eigenvalues and eigenvectors don't give you the geometric view of what is happening. Also talk to some engineering students who learned how to do matrix multiplication, but can't tell you what a vector is (it is not just something with magnitude and direction).
  4. Power travels near the speed of light. In theory, the entire globe can be connected and countries with daylight can supply those at night in a cycle.
  5. I don't agree. How can wasting your money in your twenties and thirties be more valuable than saving for an early retirement. Imagine being able to retire at 40 and do whatever you want. If you weren't stupid, your health should be good enough. Why prolong the time you have to do stupid chores for other people when you can be strategic and opt out as early as possible.
  6. The act of grading itself is what's wrong with colleges. Different people learn at different paces. Forcing everyone to work at the fastest rate and then judging them for not performing is what kills interest in subjects. People should be allowed to write tests when they want to, learn at the pace they want to decide for themselves when it's time to move on, because lets face it, not everyone cares about some prof's pet subject.

    The problem is that higher education became something marketable and universities decided to sell diplomas instead of giving people a chance to learn skills they think might help them reach their goals.

  7. > I'm a paid subscriber of open AI, but it's really just a matter of convenience. The app is really good, and I find it's really great for double checking some of my math.

    That right there is why they are valuable. Most people are absolutely incompetent when it comes to IT. That's why no one you meet in the real world uses ad blockers. OpenAI secured their position in the mind share of the masses. All they had to do to become the next google was find a way to force ads down the throats of their users. Instead they opted for the inflated bubble and scam investors strategy. Rookie mistake.

  8. > let them hire the best of the best

    The sooner people realize that there is no such thing, the better. People are extremely incompetent in judging competence. With that said, the solution isn't to then just hire the person willing to do the work for the least amount of money. You americans should realize you live in a society together and have obligations to give each other chances. Plenty of bright people around. This new top down command and control culture that has taken root in the American corporate world will be the downfall of the nation. Everyone is just trying to screw over the next guy for a quick buck.

  9. Past a certain point, skill doesn't contribute to the magnitude of success and it becomes all luck. There are plenty of smart people on earth, but there can only be 1 founder of facebook.
  10. It's not the tech that matters, it's the amount of users. See snapchat vs instagram.
  11. I don't think it is that deep for Trump. His sloppiness is great for the media because his choices lead to endless content. He is great for the unofficial media because everything he does is meme worthy. It is no wonder he and Musk teamed up, both their successes come from following the same strategy.
  12. Nvidia's market value is pumped due to hype. They can use this value to raise enormous amounts of capital and make investments that boost their earnings. This impresses investors, and the cycle continues.
  13. Do you mind sharing how one goes from p/s to expected growth rate? Is it a rule of thumb?
  14. Einstein developed relativity from mathematical reasoning. A major influence was the michaelson morley experiment, which was solely done on earth. Relativity was developed in the early 1900's and the first radio telescope was made in the 1930's. Also, orbital mechanics uses mostly Newtonian mechanics and the communication of satellites is radio waves which were understood way before einstein. There is no relativity involved. Literally everything you said is factually incorrect.
  15. Why do we need radio telescopes. Satellite communications are infinitely more useful for people on earth than some research papers about things light-years away
  16. The pie isn't always growing and the pie isn't always static. There are times where either can happen. I think people are just feeling that we are entering a period where the pie will be stagnant for a while. In the short term the world might be a zero sum game.
  17. You only need engineers for those. The type of science engineers and other academics do, are very different. The best way to lose top tier engineers is to de-industrialize and flood the market for engineering labour with low cost labour from out of the country.
  18. My comment was a reply to

    > Given their current product offerings, I really don't see a way they could ever justify a $300B valuation unless they get everyone on the planet to subscribe to their $200/month plan.

  19. L comment. If every person on the planet subscribed to the $200pm product, OpenAI's revenue would be 16.8 trillion dollars (used 7bn people x $2400pa). Would be hilarious for a company making that type of revenue to be only worth 300bn.

    Let's look at it from another perspective. It's not uncommon for tech companies to be valued at around a PE ratio of 30. This would mean a company worth 300bn should make about 10bn in profit each year. Chatgpt's usage is as ubiquitous as products that make 100's of billions in profit such as google search and instagram, does the valuation really seem that insane? OpenAI just needs to open the ad flood gates and suddenly no one is laughing anymore.

  20. This is the reason I dropped out of my masters program. There isn't room for exploration and looking for beauty anymore. Everything is about production throughput.
  21. This will probably never get the image quality of either of those. The image quality you get is proportional to the density of the detecting elements. These types of infrared methods usually have to touch the skin, so you would need a flexible array of detectors and your not going to get the same quality with that.
  22. Not a chance for MD's. MD's are the only degree where jobs are guaranteed, but graduation is not. They will always have a shortage.
  23. She is a great politician given the attention she can grab from the media. The primary goal of politicians is to get votes and she seems to be excelling at that.
  24. I'm a EE masters student and I also want to reinforce how inaccessible EE is and that I don't really recommend it as a hobby. EE is a very mature field and it's very math heavy for a reason. The second you move past the hobby boards, stuff becomes really difficult and really expensive really fast. If your end goal is to create toys for kids, then it's fine as a hobby. But without the formal training and lab access you are going to struggle to get past that point so it's pretty much impossible to turn the hobby into something more. Unlike software, where tinkering genuinely has the possibility of turning your side projects into careers. Hell, if you don't live in EE hotspot locations, I wouldn't even recommend it as a career anymore. Software is where it's at, even in the age of AI.
  25. Like most things in life, the profit that companies make follows a decaying exponential, the so called power law. Most of the money is in the big winners.
  26. Jevin's paradox isn't guaranteed to take effect. It is an observation that sometimes occurs, not a tool for prediction.
  27. In the article he mentions there is a well at the house. Also blankets and wood fires are free heat.
  28. > Yes, but some people want all the benefits with none of the side effects

    Life is about making tradeoffs. There is no such thing as a free lunch, except while you are still a child.
