Do people these days still know O’Reilly books? I’ve seen a few posts over the past couple years that are essentially asking “how did you figure out how to program without Stack Overflow?”
We usually know O’Reilley as that one annoying website that opens up with minimal information and a pointer to some chapter in some book of theirs that you need to buy to solve the question you asked
In all seriousness, people do know it exists but free/cheap online educational content is surprisingly accessible now so nobody really migrates towards textbooks anymore. Although I do admit that occasionally books have a lot of useful information that is very hard to obtain otherwise
