If I may monopolize this discussion for another moment:
I am reminded of Groucho Marx’s assessment of the educational value of television. I paraphrase:
I find television very educational. Every time somebody turns on the set, I go into the other room and read a book.
(apropos of nothing except the previous quote)
He also said, and I paraphrase again:
Outside of a dog, a book is a man’s best friend.
Inside of a dog, it’s too dark to read.
