I think the current situation is that students still need textbooks to get up to speed on a new field, since the textbook takes the time to pedagogically explain the initial assumptions of the field which the practicioners don’t take time to spell out in the articles they write. People already familiar with the field can come up with questions that have concise answers they can understand, so they can just google up the relevant articles and don’t need to rely on books that much.
