The other day I was clearing debris from a fenceline. I turned over a rotten log to reveal a termite nest. I watched for a moment as the panicked insects scurried about with their larvae and such, then kicked their home aside and went about my business.

This is what First Contact will be like for us. If we're lucky. Note that I didn't bother to exterminate the critters.

70 to 100 microprocessors? I imagine that this is true only if you employ a fairly broad definition of "microprocessor" and note that the vast majority are single-purpose devices in self-contained systems. I doubt that the "microprocessors" and "lines of code" that run the stereo or the climate-control system - or even the airbags - have any connection with the driveline.
