In one such shop I saw lots of books in the window. I was reminded that humans have to read books. They actually need to sit down and look at each word consecutively. And that takes time. Lots of time. A human can’t just swallow every book going, can’t chew different tomes simultaneously, or gulp down near-infinite knowledge in a matter of seconds. They can’t just pop a word-capsule in their mouth like we can. Imagine! Being not only mortal but also forced to take some of that precious and limited time and read. No wonder they were a species of primitives. By the time they had read enough books to actually reach a state of knowledge where they can do anything with it they are dead.
