Slow computing.
A computer should wait for you.
The machine is patient.
A computer is the most patient object in your house. It will hold a half-written letter for ten years without complaint. It does not care whether you answer in a second or in a season. It never sighs.
The impatience is not in the machine. It was added later, on purpose, by someone else, and it can be taken back out.
Who initiated?
Every urgent thing on your screen was put there by a person who wanted your attention before you had decided to give it. The interrupt was invented so that machines could serve people without making them wait. Then it was turned around and aimed at the person.
The test takes one question: who initiated? If you did, the computer is working for you. If you did not, look closer at who is.
Give the session an ending.
Sit down with a sentence in your head. I am here to write to my brother. I am here to learn how the pump works. I am here to play, on purpose, for an hour. When the sentence is finished, stand up.
A session with a reason has an ending. A session without one has only an interruption, and you will not get to choose it. None of this is against computers. A chisel does not decide what gets carved.
It is some hour, of some day, where you are.
This page does not care.
Come back next year. It will say the same thing.
The machine is patient.
You are allowed to leave.
