You would certainly have to sit down with numbers and equations, but that still doesn’t automatically imply that a textbook is the best way. You can derive numbers and equations via an app for example.

My question is this: if you always had the textbook’s author, who is an expert instructor with decades of teaching experience instantly available, in person, whenever you want a lesson or to be reminded of an equation or want to learn more about a subject, at no harm to him and his well-being: under which situations would you opt for the textbook?

To me it feels like a textbook is one way to store and transfer and spread knowledge, but is it automatically the best way to ever do so? Or is the textbook simply one technology, and we are still searching for the best way to teach as many people as possible with the resources and technologies at our disposal?
