i see technologies like Bitcoin and Bittorrent as examples of how you build the strength of the virtuous without people even realising that they are helping end the plague
the parasites main weapon against humans is precisely in confusion and misdirection, and dumb mechanisms that people get used to that simply weaken their ability to put their fangs into the blood stream is all that is required
nothing is ever going to remove parasites from the universe forever, except until forever, which is never going to come... but we can always decrease the number of ways they can attack us
every single person who adopts an antiparasitic technology moves the great work forward
