But so is a good book. And it costs way less. Even though searching may be quicker, having a good digest of a feature is worth the half hour I can spend browsing a chapter. It’s directly picking an expert brains. Then you take notes, compare what you found online and the updated documentation and soon you develop a real understanding of the language/tool abstraction.

In an ideal world, yeah. But most software instructional docs and books are hot garbage, out of date, incorrect, incomplete, and far too shallow.
