Sure, textbooks offer easier-to-digest summaries of the content, geared to the particular grade level of the student. They offer diagrams and illustrations and review questions and a glossary. But textbooks are always an assembly from a variety of sources, geared towards a classroom setting where the teacher leads students through the chapters and the exercises and the examinations. Neither the teacher nor the student is expected to be an expert. You just need to know enough to pass the test.
Digitizing that model of instruction changes nothing. Adding video changes nothing. Pinch and zoom and flashcards change nothing.
Once you’ve recognized that textbooks are just an assemblage of resources and that, in a digital world, there’s no reason to bind it together and publish these en masse, then I think you can see a path to liberation from that industry model. You can disassemble, reassemble, unbundle, disrupt, destroy the textbook. It is truly an irrelevant format.
