I think it's a very stark marker of what kind of president we have that, from all available evidence, Donald Trump has not read a book, as an adult. This is not someone who sits down in the evening to consider the latest bestseller, let alone Tolstoy - but who is very very active on this medium that requires no discipline and no attention and no empathy. It is all about retweeting praise of oneself or very quickly or poorly considered, ill-typed, misspelled diatribes against other people.
