My Take

Ted Kaczynski is one of those figures who genuinely unsettles me the more I think about him — not because of shock value, but because of the sheer waste of it all. A kid from suburban Illinois who tested into Harvard at 16, went on to earn a math PhD at Michigan, and by his mid-twenties was already publishing original work and landing a faculty post at Berkeley. That trajectory is almost impossibly brilliant. And then he walked away from it, retreated to a Montana cabin with no electricity or running water, and spent the next two decades building pipe bombs. The manifesto — "Industrial Society and Its Future" — is chilling precisely because parts of it are coherent; it's the work of a real mind that went somewhere deeply wrong. He died in federal prison in June 2023, and I find myself not pitying him so much as mourning what that brain could have done pointed in any other direction.
