That's rather like a premise from Heinlein's Beyond This Horizon, which is not an argument against it, just a historical note.
The idea seems plausible enough to be worth testing in animals. I don't feel very sure about how much it would contribute to a positive Singularity, but it also doesn't sound like it would increase risk significantly.
Approximately how long do you think it will take for reducing mutational load to come into common use?
Yes, but we don't want to overshoot and get a Planet of the Apes situation, or even worse create smart, fast breeding creatures.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
