I am writing this from the slow, disciplined landscape of recovery (one repaired shoulder, one sling, and one unrepairable truth): Medicine did not suddenly become fragile when AI arrived. It did not suddenly become threatened when APRNs and NPs expanded their scope. It did not suddenly become replaceable in the twenty-first century.
Medicine became fragile when institutions discovered they could dispose of physicians and still call it progress.
I know this because I was disposed of, repeatedly, systematically, and with bureaucratic precision, long before anyone whispered about algorithms or mid-levels. The fear circulating through the profession today is not new. It is simply louder. And it is being voiced by people who are only now experiencing what some of us lived decades ago. Let me be specific.
Phoenix: the day pediatrics was sold off
A large urban medical center did not “restructure.” It did not “realign.” It did not “modernize.” It sold pediatrics to a freestanding children’s hospital. Not metaphorically. Not symbolically. Literally.
Real physician voices, twice a week
Free, and one click to unsubscribe.
An entire specialty, the foundation of care for the most vulnerable population, was handed over like a line item on a balance sheet. The message was unmistakable: Pediatrics was not a calling, not a mission, not a moral obligation. It was a commodity. And commodities can be sold.
When Phoenix disposed of pediatrics, it disposed of the clinicians who carried its weight. It disposed of continuity. It disposed of expertise. It disposed of the moral spine that pediatrics requires.
A nurse practitioner did not replace me. I was replaced by a transaction.
Peoria: the erasure of autism expertise
A regional disability services nonprofit and the affiliated medical school in Peoria did not simply undervalue developmental-behavioral pediatrics. They erased it.
They forced me to work despite workplace injuries (multiple concussions sustained in unsafe clinic conditions), even when HR explicitly ordered otherwise. They ignored the medical reality of head trauma. They ignored the ethical reality of clinician safety. They ignored the legal reality of liability.
Then they dumped my salary. Not because the work was unnecessary. Not because the outcomes were poor. Not because the families complained. They dumped my salary because expertise was expensive.
And they attempted to replace thirty years of experience with one year post-fellowship. One year.
The result was predictable. It did not go well. It could not go well. Autism diagnosis by a physician (accurate, nuanced, developmentally grounded diagnosis) collapsed. And Peoria has never reconstituted. Not in a decade. Not with new hires. Not with new models. Not with new promises. They erased a specialty and never rebuilt it.
There are no pediatrician-led autism evaluation teams outside of metro Chicago. Over 1 million children in downstate Illinois live in a health disparity zone, unable to access services to evaluate autism. That means 35,000 children with autism spectrum disorders left undiagnosed in order to save $160,000 a year.
This is what disposability looks like. Not replacement. Erasure.
The military: the mirage of institutional respect
Then came the military mirage. The institution did not replace me. It did not critique my work. It did not question my outcomes. It did not challenge my expertise. It simply erased me.
Like a Mr. Clean disposable eraser. Use it. Extract the value. Wipe the surface. Then throw it away.
At the military medical center, I learned the purest form of institutional disposability: The clinician is irrelevant; only the CV matters. The resume is useful. The body attached to it is interchangeable.
I was not a physician. I was a credential. And credentials can be discarded.
The profession’s current panic is misdiagnosed
People worry now that physicians will be replaced by APRNs, NPs, or, heaven forbid, AI. They speak as though this is a new threat, a sudden existential crisis, a modern catastrophe.
But I lived the catastrophe before it had a name. The profession is not afraid of replacement. The profession is afraid of recognizing what it already did.
It replaced pediatrics with a contract. It replaced autism expertise with a vacancy. It replaced witness with silence. It replaced clinicians with throughput. It replaced mastery with metrics. It replaced vocation with optics.
AI did not do this. Mid-levels did not do this. Administrators did. The fear of replacement is really the fear of accountability, the fear that the profession will have to confront the decades it spent dismantling the very expertise it now claims to defend.
My shoulder heals; the profession does not
Recovery is slow. It is humbling. It is painful. It is honest. It forces clarity. And in that clarity, I see a profession that has not yet admitted its own role in its decline. Physicians are not being replaced by machines. They are being replaced by the belief that expertise is optional.
They are being replaced by the fantasy that a year of training can substitute for a lifetime. They are being replaced by the illusion that outcomes can be curated without competence. They are being replaced by the myth that the CV matters more than the clinician.
I have lived through the disposability era. I was its test case. I was its proof of concept.
And now, after surgery, after anesthesia, after the quiet discipline of healing, I see the profession with a clarity that is almost surgical: Medicine is not losing physicians to replacement. It is losing them to abandonment.
I was here. I am still here. And I am not done speaking
My shoulder will heal. The replacement will never deliver the abilities that my maker built in when I was created. My voice, for now, remains steady. And I will continue to bear witness, not because the profession asked for it, but because it has forgotten how.
If institutions try again to recycle me, they will find I am no longer recyclable. I have already learned to write from the margins. And from the margins, the view is clearer.
I was here. I am still here. And I am not done speaking.
