Session
Thinking is expensive: time and effort, the one budget you can't refill. So we buy discounts like heuristics, tidy stories, curated feeds, and now agents that decide for us. Every discount is rational. Every discount is also an attack surface, and for twenty years an industry has been optimizing against it: a kill chain running recon, exploit, and payload against human cognition, at machine speed, one operator per user. This talk maps that attack: who runs it, how, and why — then asks the harder question: what actually defends against it, and where those defenses could break.
