As someone who has not read a book in years and often jokes that they may never will again, I think the most valuable thing about capital-R reading is improving and expanding your vocabulary. Rereading sentences, stopping to look up words, etc. Knowing the right words to express yourself and communicate with others as accurately and precisely as possible is powerful, and I don't think consuming video affords nearly as much development of those skills (audio maybe a bit more, and video games potentially count as they can in theory contain a similar level of reading as a book).
