An Cosmic Virus
The Blight has been our top priority since its instantiation a year ago. This is not just because of the Blight’s obvious strength, the destruction and the deicides it has committed. We fear that all this is the lesser part of the Threat. There have been perversions almost as powerful in the recorded past. What truly.distinguishes this one is its stability. We see no evidence of internal evolution; in some ways it is less than a Power. It may never lose interest in controlling the High Beyo...The danger in Vinge's book is the "Blight" an godlike intelligence that is all the more dangerous for the fact that it does not evolve, but is a rot that sets in and stays.

The Chance of Error in Atomic Sized Computers
The first thing that you would worry about when things get very small is Brownian motion--everything is shaking about and nothing stays in place. How can you control the circuits then? Furthermore, if a circuit does work, doesn't it now have a chance of accidentally jumping back? If we use two volts for the energy of this electric system, which is what we ordinarily use, that is eighty times the thermal energy at room temperature (kT=1/40 volt) and the chance that something jumps backward aga...As things get very small we have to worry about brownian motion and quantum effects on the system.
