This is exactly the kind of essay Illich would have written if he’d lived long enough to watch medicine dissolve into infrastructure.
What makes this piece unsettling is not that it rejects technology. It doesn’t. The argument is far more difficult than that. It identifies the moment where care quietly becomes jurisdiction.
That distinction matters.
Because most people imagine authority is taken by force. But modern systems rarely work that way. They work through convenience, optimization, reassurance. Through the soft seduction of “help.” Until eventually the body is no longer something you inhabit directly, but something translated back to you through dashboards, alerts, graphs, scores, ranges, risk assessments.
The line that stayed with me most:
“Nothing changed in your body. Everything changed in your relationship to it.”
That is the entire mechanism.
The body can move from lived experience to audited experience without changing physically at all. And once that happens, sensation itself becomes suspect unless externally validated.
The terrifying brilliance of the modern system is that it makes alienation feel responsible.
People now experience guilt for trusting themselves.
Guilt for resting without metrics.
Guilt for eating without tracking.
Guilt for sleeping without optimization.
Guilt for feeling well despite “bad numbers.”
Guilt for not surveilling themselves hard enough.
And because the monitoring never ends, neither does the insufficiency.
What Illich understood before most people could see it is that infinite measurement does not produce peace. It produces hypervigilance wearing the costume of self-care.
That does not mean diagnostics are evil. It means tools become dangerous when they stop being tools and become interpreters of reality itself.
A thermometer is useful.
Living psychologically underneath the thermometer is something else entirely.
The “worried well” section is especially important because it names a phenomenon many people feel but cannot articulate: the transformation of healthy individuals into permanent pre-patients. Not sick. Not dying. Just endlessly managed.
And that creates a civilization of people increasingly disconnected from their own internal signals while simultaneously obsessing over them.
The final question lands because it forces a confrontation modern culture avoids:
“If the data says you are failing and your flesh says you are fine, which one is you?”
That is not merely a medical question anymore.
It is philosophical.
Political.
Spiritual.
Even existential.
Because underneath all of this is a deeper issue:
whether human beings are still allowed to possess first-person authority over their own existence.
Beautifully written. Precise. Controlled. And deeply important.
Yes...so true. Combined with the oncoming juggernaught of IA and one has good reason to pause and wonder where and how it will all end. One thing seems sure. Human beings are slowly relinquishing agency to something they can't see or really know.
The jurisdiction framing is sharp. Wearables can be useful, but there is a real cost when a number gets final authority over felt experience. The body becomes less something inhabited and more something audited. That distinction between data as input and data as sovereign feels essential.
Terrific essay about one of those things that you have an ongoing sense of but were just never able to put a name to. I've now joined the ranks of the worried well. As proof, I have spent the last few week wondering when my PCP's office is going to call asking me to schedule my annual checkup. Never mind...I think still have a good sense of my body...I'm pretty sure I'll be able to tell if something is really off. the system has not taken away my agency on that front.

I just gave a presentation on this topic.
