Straw man. Who the hell uses their todo list like that? Who are those "proponents" who suggest playing this sort of silly "estimate the task and match it to a time slot" game? I've never met one.

You've never seen a Gantt chart? You're lucky, then.

A Gantt chart is not a todo list. And a todo list is not a Gantt chart. Ranting against the evils of over-planned projects is one thing. Equating that to the humble todo list is not only silly, it's also very wrong. Terrible advice.
