Unabomber not Unibomber, not that it matters. Ted Kaczynski, the man you are referring to is a fascinating man, try to ignore all of the recent hype and delusion following that Netflix series. I encourage everyone to read his book "Industrial Society and Its Future", he is without a doubt a luddite but presents some very compelling reasons in the book, if nothing else it will give you some insight into a rather notorious but perhaps unfairly represented character.
