>Think about owning horses back in the day, which you could simply breed to get more of. You could travel freely pretty much anywhere, no roads required. Compare that to a car which is manufactured somewhere far away with tons of special expertise and which basically cannot be repaired by a layman anymore (as opposed to not too many decades ago). And you rely on a huge infrastructure network for building and maintaining the roads.
How about the externalities and technological advancements nessecary to domesticate wild horses, and also the infastructure networks which drove the need and ability to create a ship capable of transporting those horses across the Atlantic ocean to America, where they are not a native species.
Had Kaczynski not conducted his campaign of bombings he would have had no leverage to get the Washington Post to publish his manifesto.
I re-skimmed the manifesto earlier today. It's not uninteresting, but I don't think it's the sort of thing which can be considered or appreciated outside the context of his violent acts. For one, no one would have read it if Kacynzski had been a nonviolent academic.
As for bitterness and anger, well, here's a quote I pulled somewhat randomly from the text.
"We have no illusions about the feasibility of creating a new, ideal form of society. Our goal is only to destroy the existing form of society."
I think the risk is more that the people will read Dahl or watch Spielberg and think that the cultural sensitivities from the 1960s-1980s we're exactly like those during the 2020s.
