Elon Musk on reading books, in The Book of Elon by Eric Jorgenson: Read books, because the data rate of reading is much greater than when somebody is speaking. What’s the output rate of speech? A couple hundred bits per second, maybe a few thousand per second if you’re going full tilt. You can get several times that by reading. The main reason I didn’t go to lectures in college was because the data rate was too slow.
