Now for my personal take on the whole thing. A lot of the book is filled with musings about the state of our current lives and how, recently, as human beings we've transitioned from relying upon memorized tales to transmit our histories to writing down basic texts to now relying on the complex external web of collected human intelligence for most of our memories. Now there is no saying that one is right and one is wrong. There is only what has been and what is. What is, is the slow dependence on machines to tell us the things we once memorized so easily. Just think how a photograph holds a single memory in time for us to look at externally whenever we like, that didn't exist 200 years ago (aside: I had to look up when photography was invented because I didn't remember if it was 1 or 2 hundred years ago). But now we have pruned away much of the skill of memory as a general necessity of life and though the likes of socrates would surely rue our fate, there is no saying what lengths this open expanse of mind can be put to.
I personally hope to dedicate all the waking energy of my mind to new episodes of Mob Wives and Jersey Shore.
