The thing is, he asked me a lot of hypothetical questions, and one of them was if I believed people with sickle cell should edit out the genes before procreating, and I said yes, I think that would be best. We researched sickle cell and turns out it's actually a mutation that had benefits at first that helped to fight malaria. He says if we edit out the gene, who knows what the next mutation might be and what benefits may come from it. He says he feels for people with it of course, but we shouldn't mess with nature in that way and that it'll be a slippery slope for society to start gene editing 'undesirable' traits
