Anyway, I just finished reading Kaczynski's first book, "Technological Slavery" (Feral House, 2010) It's an amazing work and it elaborates on this point quite a bit. Recommended.
You might also want to check out his most recent work, "Anti-Tech Revolution: Why and How" (2016)
Here's what MIT's student newspaper had to say about the book:
"Anti-Tech Revolution: Why and How is Kaczynski’s well-reasoned, cohesive composition about how revolutionary groups should approach our mercurial future….. I recommend that you read this compelling perspective on how we can frame our struggles in a technological society." -- The Tech, MIT's oldest and largest newspaper
"batshit crazy" haha. A political classification if there ever was one.
