Meet Your Descendants
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.
So says science fiction author Charlie Stross:
And yet, these trends are emergent from the current direction of the telecommunications industry, and are likely to become visible as major cultural changes within the next ten to thirty years. None of them require anything but a linear progression from where we are now, in a direction we're already going in.
What would enable a future in which, as Stross suggests, we face a "danger of losing the concepts of privacy, and warping history out of all recognition"?
Among other things, Stross says we can expect to see:
...lifelogs, ubiquitous positioning and communication services, a civilization where every artifact more complicated than a spoon is on the internet and attentive to our moods and desires, cars that drive themselves, and a whole lot of other mind-bending consequences. All within the next two or three decades.
And all of it driven by radically expanded abilities for storage and retrieval of information:
My model of a long term high volume data storage medium is a synthetic diamond. Carbon occurs in a variety of isotopes, and the commonest stable ones are carbon-12 and carbon-13, occurring in roughly equal abundance. We can speculate that if molecular nanotechnology as described by, among others, Eric Drexler, is possible, we can build a device that will create a diamond, one layer at a time, atom by atom, by stacking individual atoms — and with enough discrimination to stack carbon-12 and carbon-13, we've got a tool for writing memory diamond. Memory diamond is quite simple: at any given position in the rigid carbon lattice, a carbon-12 followed by a carbon-13 means zero, and a carbon-13 followed by a carbon-12 means one. To rewrite a zero to a one, you swap the positions of the two atoms, and vice versa.It's hard, it's very stable, and it's very dense. How much data does it store, in practical terms?
The capacity of memory diamond storage is of the order of Avogadro's number of bits per two molar weights. For diamond, that works out at 6.022 x 1023 bits per 25 grams. So going back to my earlier figure for the combined lifelog data streams of everyone in Germany — twenty five grams of memory diamond would store six years' worth of data.
Six hundred grams of this material would be enough to store lifelogs for everyone on the planet (at an average population of, say, eight billion people) for a year. Sixty kilograms can store a lifelog for the entire human species for a century.
In more familiar terms: by the best estimate I can track down, in 2003 we as a species recorded 2500 petabytes — 2.5 x 1018 bytes — of data. That's almost ten milligrams. The Google cluster, as of mid-2006, was estimated to have 4 petabytes of RAM. In memory diamond, you'd need a microscope to see it.
So, it's reasonable to conclude that we're not going to run out of storage any time soon.
If Stross is right, and there seems little reason to think he's not, then diamondoid nanotechnology will have a huge impact not only on our environment, our economy, our military, and our health care, but also on how we live each day and even how we think about our lives.
