The ultimate problem is that the paradise the Kaczynski is offering, the solution to civilization so to speak, is the tiny, smoky, dingy, smelly wooden prison cell that absolutely nobody else wants to dwell in. It is a paradise billions are fleeing from. Civilization has its problems but in almost every way it is better than the Unabomber’s shack.
The Unabomber is right that technology is a holistic, self-perpetuating machine. He is wrong to bomb it for many reasons, not the least is that the machine of civilization offers us more actual freedoms than the alternative. There is a cost to run this machine, a cost we are only beginning to reckon with, but so far the gains from this ever enlarging technium outweigh the alternative of no machine at all.
