Codex estimates a 2-4 day task, then finishes it in 3 minutes

A lighthearted AI coding anecdote: the author asks Codex how complex a task is, and it replies "Moderate. I'd budget 2–4 engineering days." The author says "ok do it" — and Codex works for just 3 minutes before reporting "done."
The contrast went viral as a joke, but it also hints that coding agents' self-assessments of task complexity tend to be overly conservative.
