Theodore Kaczynski, PhD was no poseur. He wasn't one of those fake Luddites, who only claim to hate modern technology but can't go three days without HBO. Ted practiced what he preached. You have to give him that.
The Unabomber's manifesto, submitted to Penthouse magazine and a couple of newspapers, identified a bunch of pet peeves: overcrowding, dissociation from nature, social conformity, rapid pace of technological change, consumerism, corporate domination, etc.
Ted was a true believer. He cranked out that diatribe in a one-room, 10-by-12 plywood shack situated on 1.4 acres of Montana forest. The cabin had no electricity or plumbing. He used a manual typewriter.
Oh! Did I mention that he killed a bunch of people over the years with homemade bombs? Aw, shit. Well, he did.
