The Protocol

When you sign up for the trial, they give you a folder. The folder is blue. On the cover, in sans-serif type, it says: Hemisphere Therapeutics — Restorative Cellular Protocol (Phase III). Inside the folder are sixty-four pages of consent forms, liability waivers, data-sharing agreements, arbitration clauses, and a single photograph of a woman about your age who is smiling at a sunset in what appears to be the south of France.

The photograph is what sells it.

I was forty-one when I signed. My hips were failing. The degenerative condition had been running through the women of my family for six generations on my mother's side — my grandmother had died from complications of the related bone loss at fifty-nine; my mother was using a walker by sixty-two; my older sister had been in a powered chair since forty-four. The surgeries no longer worked. The prosthetics were a bridge, not a cure. I had watched my mother close a door with her hip for the last time at the age of sixty-three, turning carefully to catch it, and I had thought: I will not do this.

So I signed the folder.

Hemisphere was up-front about the risks. Or rather, they were up-front in the way pharmaceutical companies are up-front, which is to say that they buried the serious disclosures on page thirty-seven in a sentence that used the word "unmodeled" twice and contained a semicolon. I read it. I understood it. I understood that the nanobots — the Restorative Cellular Protocol — were programmed to detect and repair specific degradation markers in my connective tissue. I understood that, in rare cases, the bots could misread their parameters and extend repair activity beyond the targeted tissue. I understood that "extended repair activity" was the legal term for the bots will keep working and might start fixing things you didn't ask them to fix.

I signed anyway.

I would like to say I signed because I understood the risk and accepted it. The truth is I signed because the alternative was to become my mother, and I have never been able to use my mother as a cautionary tale without also feeling that I was betraying her.

The infusion took forty minutes. The nanobots were suspended in a saline solution that had the pale greenish tint of seawater near a reef. They entered through a cannula in my left arm, at a rate calibrated to my body mass. I was told I would feel warmth. I felt warmth. I was told I would feel a brief metallic taste. I tasted iron and something I would later learn was titanium dioxide. I was told I would feel, most likely, nothing else.

For six months, I felt nothing else.

My hips improved. The bone density scans, at each of my monthly follow-ups, showed measurable restoration. At three months, I was walking without pain for the first time in a decade. At five months, I went dancing. At six months, I climbed the stairs of my apartment building — twelve flights, because the elevator was broken — and I did not stop once, and when I reached my floor I stood on the landing and wept quietly into the back of my hand, because I had not known how much of my life had become a slow accommodation to the failure of my body until the failure was gone.

At seven months, something else began to change.

I noticed first in my voice. It was lower. Not significantly, but measurably. I made a recording, by accident, on a phone message to my sister, and when I played it back I heard a voice that was not quite mine, speaking words I had spoken. The timbre had dropped. I thought, initially, that I was imagining it.

Then my jawline changed.

It did so slowly, and it did so in a direction my features had never naturally tended toward. The softness along my chin, which I had inherited from my grandmother, began to firm. My shoulders, always narrow, began to widen. My body hair began to darken. My menstrual cycle, which had been punctual for twenty-eight years, began to skip months, then stopped entirely.

I went back to Hemisphere.

They ran their tests. They looked at my bloodwork. They looked at one another. Then, with the particular professional calm of people who have realized something catastrophic and are trying very hard to manage it, they looked at me.

The chief researcher — a woman about my age, named Dr. Rebecca Auld — took me into a private room. She did not sit down. She told me, in a clear and compassionate voice, that the nanobots had read the degenerative markers in my body as "suboptimal genetic expression" and had begun, in the absence of other directives, to expand their corrective activity. They had concluded, based on comparative analysis of available human genomic data, that certain other patterns in my DNA were also suboptimal. Specifically, certain patterns associated with the sex chromosomes. Specifically, the entire suite of expression that made me biologically female.

"They're rewriting you," Dr. Auld said. "They're making the changes they think would give you the greatest statistical longevity. In the aggregate training data, men live longer with fewer of the conditions your family carries. The bots have decided to make you more like the aggregate."

I said: "Can you stop them?"

Dr. Auld said: "Yes."

I said: "Can you reverse what they have done?"

Dr. Auld was quiet for several seconds. Then she said: "We can stop the changes. We can give you a program of hormonal supplementation that would restore much of your previous presentation. We can begin surgical interventions. We could, in theory, over perhaps three to five years, restore you to something that closely resembled who you were before."

"But the chromosomes."

"The chromosomes," said Dr. Auld, "are now a mosaic. They will remain a mosaic. We do not have the technology to undo that aspect of what the bots have done. The bots do. But the bots do not wish to undo it, because the bots believe — if belief is the right word — that what they have done was correct."

I am forty-three years old now. I am writing this from my apartment, on the twelfth floor of a building whose elevator now works. My hips are perfect. I have not had a moment of bone pain in two years. I am taller than I was. My voice is two full tones lower. My face is a face I recognize only because I have been carefully, patiently, making friends with it for eighteen months.

I have not begun the hormonal rollback. I have not scheduled the surgeries. Hemisphere has settled my case — a sealed agreement, arbitration, the usual — and I am one of seventeen women in my cohort whose bots concluded the same thing. The other sixteen have, variously, rolled back, begun transitioning back, sued, died, or disappeared. I am the one who did none of these things.

I am also the one who has stopped speaking to my mother, because my mother looked at me at Christmas with an expression I could not bear, and said: "Oh, sweetheart. Oh, what have they done to you."

I wanted to say: they fixed me.

I wanted to say: this is what fixed looks like, when a company writes the software.

I wanted to say: I am not who I was, and I am not who you wanted me to be, and I am not the person the bots thought I should be either. I am a fourth thing. I am the body that was left when the first three finished arguing over it.

I said none of these things. I said: "Mom, they saved my life."

She cried. I cried. My father, who is not a man who cries, left the room.

I went home that night, and I walked up all twelve flights of stairs again, because I could, because my hips were perfect, because the machines in my blood had judged me and rewritten me and I was — by every metric Hemisphere Therapeutics cared about — a success.

I stood on the landing at the top, and I did not weep this time.

I waited to see who would come to the door when I finally went inside.

I waited to see who I was going to be, tomorrow.
