"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Today population forecasts are based on extensive and reliable data. However, no such demographic base exists for the world's growing population of machines and devices. Now may be the time to take machine demography seriously and enter into real discussions about machine population control.
The couple of years in question here saw one of the largest bureaucracies anywhere undergo a convulsion in which it tried to reconceive itself as a non- or even anti-bureaucracy, which at first might sound like nothing more than an amusing bit of bureaucratic folly.

I refer to small money-earning business that consist of the work of a visible individual, or have evolved from a personal hobby or skill, as "small economies". We can include in this category newer forms of at-home work—side businesses, telecommuting and the like. The amount of income is unimportant; meager profits are compensated for by the motivation of the owner. A small economy may or may not be someone's main form of livelihood, but it is always a spontaneously conceived and continuing activity.
