constraints: brains and minds, a million stellar geniuses, the creativity of a dozen ages
crammed into a single generation. You literally thought your way out of the trap ... and
into something larger.
The solution to being trapped in one solar system was a happy coincidence: simultaneous
breakthroughs in the fields of bionics and computer science. Nanoprobes allowed the
human brain to be mapped from the inside out, its configuration and software states
transmitted to any external processor complex enough to run it as a program. Your minds
are not qualitatively more complex than any other piece of software: you can run on
processors other than those developed by biological evolution. Robot spacecraft could
travel to the stars, but not in a human lifetime. But once they got there they could build
human bodies and transcribe stored human personalities back into the virgin grey matter.
A kind of reincarnation.
The ships carried Von Neumann machines; self-replicating robots programmed to explore,
spawn, and explore again. Autonomous and cheap, they visited and mapped the nearer star
systems before they and their descendants moved on, rippling outward in an expanding
sphere of exploration. Every time a probe entered and mapped a new system, it left behind
a beacon. Occasionally a probe from one family tree would enter a new star system which
had been mapped by a probe from one of the other families: recognizing the beacon, the
Von Neumann machine would switch to an alternative behaviour. Picking a suitable
airless moon, it would land and begin to reproduce. After twenty or so generations there
were enough robot factories to begin the construction of an expansion processor, a vast
solar-powered computing surface covering the entire surface of the planet. Huge slabs of
processing circuitry spread rapidly across the airless moons of gas giants. Once
completed, the expansion surface was hooked up to a gatecoder -- a laser communicator --
and signalled its readiness to the slowly-developing interstellar processor network. Which,
vast as it was, served mainly to execute a single, ferociously complex, distributed
program: the Dreamtime.
The Dreamtime was designed by Superbrights, the ultimate descendants of the first human
experminents in artificial intelligence. A remarkably complex virtual space, it provided an
afterlife fit for the senses of a human or Superbright mind embedded within it. It also
provided a transport layer: protocols to allow the transmission of uploaded human and
Superbright minds between isolated stellar domains. Uploaded travellers were transmitted
as streams of data packets, then reassembled and downloaded into cloned bodies at their
destination by a mechanism known as a gatecoder.
More subtly, the Dreamtime network also offered a back-up to reality. Nanotech encoders
proliferated on every colony world, weaving themselves into the nervous systems of the
entire population. Constantly filtering a trickle of data through decentralized, cellular
transcievers, they could provide access to the stored wisdom of the ages. They also served
to relocate the active centre of identity into the Dreamtime at the moment of death, until
