I agree for deadly genetic disorders, but we can't be sure if a harmful mutation will be important in the future. For example sickle-cell disease make people immune to malaria.
What if in the future a pandemic rises, and we have "edited away" the only mutation that would give immunity?
Why is that unlikely? As cost approaches zero and benefits increase we can assume we get pretty close to 100%. In fact holding a portion of the population back, even if well meaning, will be discriminatory.
I think because in Italy the different models are called "man bicycle" and "woman bycicle" ("bici da uomo" and "bici da donna", respectively). How are they called in English?
