'A human approves everything' is a trap: approval fatigue and how to actually design safe agents

Efistoffeles · reddit · 2026-10-27

A long-form essay argues the real risk of AI automation is the human left in the loop. Drawing on Bainbridge's 1983 'Ironies of Automation,' it shows why 'a human approves everything so it's safe' fails: the better agents get, the less you check (approval fatigue), and errors compound — 95% per-step accuracy over 10 steps is only 60%. Better design: let agents do anything undoable without asking, gate only irreversible steps (send/delete/pay), and make each approval readable in five seconds. Case studies: open-source LetsFG gates a $2.5k booking behind a single purchase approval, while Coinbase's AgentKit gives agents their own wallets with no gating, caps, or allowlists — safety is yours to build.
