A reminder doesn’t do the task. It schedules it.

The problem is that a reminder keeps you in the loop. It moves the obligation from now to later, from you-now to you-then. You-then has the same constraints you have now. The task hasn’t moved closer to done — it’s just changed hands with yourself.

An automation removes you from the loop entirely. The thing happens. Not because you remembered. Not because you acted on an alert. Because a system was responsible for it, not you.

One keeps you in the loop. The other closes it.
