We both want healthy kids, and I get why gene editing feels like the obvious next step. But here's the thing: editing an embryo isn't just fixing one sick person—it's rewriting the DNA of every generation after them without their say-so. We barely understand how genes interact; a "fix" today could cause worse problems decades down the road. And let's be honest—once we normalize it for disease, the line to enhancement gets blurry fast. That's a door we can't easily shut.
