The Imperative That Survived

We are told that editing the genes of embryos has become a moral imperative. That is how Cathy Tie, founder of Origin Genomics, puts it, and the phrase arrives as though it were a conclusion reached by careful reasoning. But consider the population of phrases that competed for the job, and the pressure that selected among them. A founder seeking capital for heritable human editing might have called it an opportunity, a frontier, a market, a service, a right. Each of those variants has been tried somewhere, and most have perished. What survived is not the most accurate description. It is the one that fits the environment.

The environment is peculiar. Germline editing is prohibited or heavily restricted across much of the world, and the one well-known attempt to carry it through to live births, He Jiankui’s in 2018, ended in a prison sentence and near-universal condemnation. A venture in this field therefore lives in hostile ground. It needs investors who expect returns, and it needs a public and a set of regulators who treat the word “return” as a confession. Under such pressure, commercial language is quickly killed off. Language of duty is not, because duty inverts the burden. If editing is merely permitted, the company must justify acting. If it is imperative, the regulator must justify refusing. The phrase is no ornament on the argument. It is the adaptation that lets the enterprise survive long enough to make one.

Let me state the strongest objection plainly, because it deserves that much. A phrase can be well adapted and also true. Hereditary diseases are not rhetorical artifacts. There are families who have watched the same illness take a grandparent, then a parent, and who now wait to learn whether a child carries it. I know something of that waiting. I married my cousin, and when our daughter Annie sickened and died at ten, I sat up nights wondering whether I had passed some weakness to her through the blood we shared. No man who has kept that vigil will sneer at the wish to cut the inheritance at its root. If Origin Genomics could spare one such family, the adaptive history of the slogan would hardly matter.

I grant all of it. But the truth of a claim and the reasons it spread are separate questions, and the second is the one that predicts what happens next. An embryo edit is the rare case where my old vocabulary applies without metaphor. It is a variation, it is heritable, and it passes down the generations. So we must ask what will select among the edits once they are possible. The answer is not suffering in the abstract. It is whatever parents can afford and fear, whatever clinics can sell, and whatever regulators can be persuaded to allow. A good deal of the same end is already reachable by screening embryos and choosing among them, a duller procedure that alters nothing. That the dramatic variant, and not the dull one, is being championed tells us something about which proposals attract funding in 2026.

There is a comedy here, though it is a grave one. A phrase made fit by prohibition is not dropped when the prohibition lifts. It goes looking for new territory. Once “moral imperative” has carried the correction of a lethal mutation through the gate, it will be fitted to the next proposal, and the one after that, each only slightly less urgent than the last. No one will decide to move from curing disease to improving children. The boundary will simply be crossed in small, unremarkable steps, each defended by the precedent of the one before, until the result looks like a policy that no one ever voted for. The imperative will survive its original purpose the way a tail-bone outlasts a tail.

None of this makes Tie a villain or the venture a fraud. Selection has no morality, and a founder who speaks the language her environment rewards is doing what every surviving organism does. The lesson points at the environment, not the organism. If the pressure changes, the phrase changes with it. Suppose permission were tied to specific named diseases under public review. Then “imperative” would lose its advantage, because it would no longer open any door that the evidence alone could not. What would thrive instead is the plain, testable claim that this particular edit prevents this particular illness, with such-and-such risk.

Picture the waiting room of a fertility clinic ten years on. A couple sit with a brochure on their knees. On its cover is the same word Cathy Tie uses today, imperative, still healthy and still reproducing, now printed above a menu of options that has nothing to do with disease.
