Disclaimer: AB + BC may be longer than AC It's the opposite ! The triangle inequality doesn't always hold when it comes to learning (unless you meant longer = you learn more, here I meant longer = you spend more time / efforts on it) This begs the question, when we learn new knowledge “efficiently” and “quickly”. How much knowledge did we really acquire? Good question. Sometimes a real breakthrough can also happen without working really hard, it's just not very common. And some of the knowledge you got can be useful quite quickly in your daily life or profession, so there are definitely /some/ benefits in learning efficiently. Ee'll always need to simplify some past discoveries / knowledge and focus our time / energy on more complex problems. Our children will get access to much more knowledge than us anyway, it's all about explicitly deciding where our efforts should be focused on. Some people might loose, some might win. I think it's related to your last link https://perell.com/note/the-paradox-of-abundance/ https://perell.com/note/the-paradox-of-abundance/ in abundance, the ultra smart will rise, the median people will fall behind. For now, I would like to produce more high quality learning material. But if I had to mentor someone to learn stuff, I wouldn't always recommend to constantly look for a ready-made answer online for example.
