seti hackers
i have mixed feelings about seti. on one hand, i'm pretty sure the chance of detecting an alien signal is effectively zero. a baseball could theoretically quantum tunnel through a glass window but the odds of it actually happening are also effectively zero. on the other hand, seti is such a romantic idea that people are donate their disposable income on it and in a bizarre twist finance real astronomy. most seti people are cranks, mostly harmless. this entry was inspired by the latest seti crankitude: we need to be really careful with the signals we haven't found yet because some malevolent et could take over our computers and/or beam themselves here.
