Please forgive a somewhat stream of consciousness philosophical discussion.
Over at my book blog, I have posted a review of Permutation City, a book that seems to be out of print. I will assume you haven’t read it, and I will avoid spoilers in case you want to find a copy. For what it’s worth, I rated it “3: worth reading once (check it out from a library).”
The main focus of the book is on uploads, or “Copies” as they are called there. You upload a scanned copy of your brain onto a computer, thereby having a backup in case you die. When you fire up your Copy, there is a version of you that exists on a computer. I want to focus on a single thing, the character of Peer and how he goes about being happy, since it applies to what we talk about here. Peer joyously instantiates the purest form of the grind.
