Matrioska Brain

Quote rom the 200 science fiction novel "Accelerando" by Charles Stross:

• "... The solar system is a dead loss right now – dumb all over! Just measure the MIPS per milligram. If it isn't thinking, it isn't working. We need to start with the low-mass bodies, reconfigure them for our own use. Dismantle the moon! Dismantle Mars! Build masses of free-flying nanocomputing processor nodes exchanging data via laser link, each layer running off the waste heat of the next one in. Matrioshka brains, Russian doll Dyson spheres the size of solar systems. Teach dumb matter to do the Turing boogie!"

Er, no. This is a reference to Robert Bradbury's Matrioshka brain concept, which presumes incandescently hot Drexler-style rod logic - presumably as a placeholder for something that might actually work efficiently at high temperatures without chemo-mechanical decay.
