The YouTube tutorial is the perfect emblem of this rot. Tutorials are not documentation. A tutorial teaches you to perform a specific sequence of steps to achieve a specific outcome. The steps are usually correct for the specific scenario the tutorial covers. If your scenario differs — if something’s changed, if you get an error the tutorial didn’t anticipate, if you’re using a different version — the tutorial has given you no tools to respond. Documentation teaches you to understand a system: what its components are, how they interact, what the configuration options mean and why they exist, what the error messages indicate. One produces people who can follow instructions. The other produces people who understand what they’re doing. The industry has enthusiastically replaced the latter with the former and called it democratization.
