Just to be clear about one thing here, piracy is robbery committed at sea. Although common usage has warranted the terms be placed in the modern lexicon; "software piracy", "pirate radio", and like terms are metaphors. There are, of course, many terms for robbers and thieves on land, the aforementioned "brigand" among them.
Piracy most likely started as soon as the second boat was launched, and will most likely continue until there is only one boat.
Those who cannot remember the past are condemned to repeat it.
-George Santayana
