Contrary to popular belief, the Unabomber was more of a domestic terrorist rather than a psychopath. As with all terrorists, his motive to kill was purely ideological. He was severely critical towards technological advancement and how—in a way—technology would corrupt society. It might've seemed like an absurd and irrational critique 30, 20 or even 10 years ago, but now in 2021 where nomophobia is a real thing, the Unabomber's critique isn't that far off (just minus the terrorizing part).

If the Unabomber didn't choose the unnecessarily violent path, he would've made a great point. Many theorists have talked about the paradox of technology, where technology has freed us, but yet at the same time has enslaved us.

It is recommended to read Neil Postman's "Technopoly: the surrender of culture to technology" to understand more about this paradox.
