I just think we're messing with something we don't fully understand, and once you start editing embryos, where do you draw the line? It feels like it could make things really unequal, and that makes me nervous. Maybe I'm wrong, but that's my gut feeling.

Remember those CRISPR twins in China a few years back? That was a real case of editing embryos and it shocked everyone. If mistakes happen like that, I just think we shouldn't be going down this path. Maybe you have a point, but that example stuck with me.

Maybe you're right that I'm overthinking it, but imagine if an embryo edit goes wrong and that person has to live with the mistake forever. That risk seems too big to me, even if I can't fully explain why.
