I spent a very long time getting into the weeds to learn everything about computer architecture, because at the time it seemed like it was the only way to do it and I wanted to have a career. In the meantime social media / cloud hosting / StackOverflow were invented, it became much easier for people to write online, and it turned out I didn't need to do any of that because the actual authors have all explained themselves on it.

Though, doing this is still the right way to learn how to debug things!

nb I actually just realized I never understood a specific bit of image processing math after working on ffmpeg for years, asked a random AI, and got a perfectly clear explanation of it.
