I am actually reading a paper book right now to learn about configuring advanced features of ZFS. Hard to believe but it’s much easier to understand than the fragments of information on Stack Exchange. The man pages are nice to reference but they don’t really teach the concepts or give good examples. And Perplexity gave me bad information. Even for very technical things, which you might think would be the first to be displaced, there’s still a place for paper books. Yeah I could figure it out eventually but reading this book has probably been faster, more thorough, and more approachable.
