The minutes you spent on Instagram last month, in friends you could have called

Open Screen Time. Look at last month's Instagram total. Most users I show this to are at fourteen to eighteen hours.

Now divide by forty-five minutes. Forty-five minutes is what a real phone call with someone you have not spoken to in over a year looks like. Long enough to actually catch up. Long enough that they remember the call.

Fourteen hours of Instagram is eighteen catch-up calls with people you have not heard from in over a year. Eighteen friends. Eighteen siblings, parents, ex-colleagues, university roommates, neighbours-you-meant-to-stay-in-touch-with.

You will not make those calls. I am not asking you to. I am telling you that the budget you spent on watching strangers eat breakfast was exactly the same budget that would have closed those eighteen loops in your own life.

This is not a guilt-trip post. Guilt-trip posts are an Instagram product. I am here to do the maths.

Why the substitution is the whole story

The objection at this point: "But I would not have called those eighteen people. I would have done something else with the time. Sleep. Work. Sit on the couch."

Probably true. The substitution rate from "minutes saved on Instagram" to "minutes spent calling a friend" is not 1:1. It is closer to 1:10. Save ten hours and you might invest one hour in a relationship that needed it.

But the rate is not zero. It is bounded below by zero in only one direction. Every hour you do not save on Instagram has a substitution rate to "called a friend" of exactly zero. The minutes were spoken for. Strangers' breakfasts had first claim.

The first hour you reclaim does not call a friend. The second hour might not. The fifth hour starts to. The tenth hour, you notice you have not spoken to your dad in three months, and you call him, and the conversation goes for an hour, and three things happen.

He sounds better than the last time. You sound better than the last time. The relationship is in better repair than it was at the start of the hour.

You did not get those three things on Instagram. You were never going to. The interface does not produce that output, no matter how long you stay.

What disappears

The full inventory of what you lose to the platform is not just the friends. It is everything that requires sustained low-intensity attention.

Letters and long emails. Drawings made for nobody. Conversations with strangers on planes. Walks where you actually noticed the architecture. The slow read of a novel where you let the chapter land before starting the next. The first half hour after sex. The whole hour after the funeral. The morning you were supposed to think about whether you still want to be at this job.

None of these things compete with Instagram on the metrics Instagram cares about: retention, engagement, return rate. All of them compete with Instagram for the same minutes. Instagram is winning because it has been engineered to win and the others have not.

The lever

There is no version of this problem where you ask the platform to give back your minutes. The platform is not in that business. You have to put friction on your side of the line, and the friction has to be costly enough that the platform's optimisation cannot route around it.

A dollar a week. Fifty cents per overage block. The minutes you save are minutes you decided to save, in the moment you would otherwise have decided to spend.

What you do with the minutes is your business. The eighteen calls are still there. They will keep being there until they are not. Make of that what you will.
