Manhattan Genomics and the New Ethics of Creation

We examine the rhetoric and practice of human germline genome editing through the lens of a biotechnology start-up invoking the Manhattan Project, a metaphor equating compassion with technological mastery. Drawing on our experience in assisted reproduction, we contrast this emerging “ethic of eradication” with the established ethic of selection embodied by pre-implantation genetic testing (PGT). Whereas PGT prevents suffering through diagnostic restraint, germline editing seeks to correct biology itself, transforming patients into prototypes and clinicians into engineers. We argue that this shift redefines reproductive responsibility, expanding it from avoiding harm to perfecting inheritance. Governance of germline innovation must not rest on private moral entrepreneurship: corporate claims of compassion must yield to professional accountability, precaution, and public oversight. Science is never politically neutral. The capacity to edit inheritance demands not boldness but restraint, the willingness to pause, remains the truest expression of compassion in reproductive medicine.
