I see, but why is it unrealistic tho ? And are there any possibility for that to work ?

With that said what things will we able to do by combining CRISPR , nanotechnology and computerized artificial Intelligence What kind of possibilities will open ?

Can we change things like our species(Example a cat to dog) , our appearance , personality , gender , age etc after we've completed our biological development ? And even if we do manage to edit every cell in the body or every gene in an adult ( for complex traits of course) Would changing the DNA even have a major effect and give us the desirable traits we want ? Will it ever be possible ? Using nanotechnology combined with genetic engineering ?
