A long but interesting speech by SF author Charles Stross on the future and what it holds. His main thrust is that of life-logging, technology converging to provide humans with vast amounts of external storage, information access and key tools. Remember MIT's Wearable Computer Project where a bloke walked round with several tens of kilos of badly hacked Pentium wrapped round his body? Well, nothing like that.
Total history — a term I'd like to coin, by analogy to total war — is something we haven't experienced yet. I'm really not sure what its implications are, but then, I'm one of the odd primitive shadows just visible at one edge of the archive: I expect to live long enough to be lifelogging, but my first forty or fifty years are going to be very poorly documented, mere gigabytes of text and audio to document decades of experience. What I can be fairly sure of is that our descendants' relationship with their history is going to be very different from our own, because they will be able to see it with a level of depth and clarity that nobody has ever experienced before.
Meet your descendants. They don't know what it's like to be involuntarily lost, don't understand what we mean by the word "privacy", and will have access (sooner or later) to a historical representation of our species that defies understanding. They live in a world where history has a sharply-drawn start line, and everything they individually do or say will sooner or later be visible to everyone who comes after them, forever. They are incredibly alien to us.
