> I still wouldn't worry about it for humans, though, as simple genetic testing and further editing could counteract it. It might not show up in genetic testing unless you knew what to look for. And if you found some modification, currently it would not be ethical to try to reverse it in the germline (because these gene editing techniques are not perfect and can introduce potentially deadly errors). I think it is worth thinking more seriously about what we would do to counteract gene drives in humans, whether caused by neo-Nazis, terrorists, or well-meaning parents. Gene drives in other species, wild or domesticated, could are more of a threat in the short term.
