>>1650This is a great point that other people haven't mentioned. If I wrote a advanced book on how to develop a large semi-specific project and use libraries to do so, I would be working for almost nothing.
By this I mean, if my choice is to make 100k working at a company on a project over the course of a year. VS, I make maybe 20k max on a book doing the same programming work BUT with the added cost of doing a writeup about said work? I'm losing money, big time. This is probably a good incentive for why books only often have simple examples. It doesn't pay well enough to create large extensive ones.
