Not too much, tbh. It's less Jonah Lehrer, "why smart people are dumb" stuff and more of a historical look at the transmission of information throughout history.

Chapters discuss, among other things, English dictionaries, Charles Babbage and Ada Lovelace, the telegraph, and memes. Great read.

EDIT: saw that you're bored of reading business and tech books. This is definitely a breath of fresh air--it unquestionably falls in a different category than "Switch" or "Rework."
