Gene modification is a tool, capable of use for good or evil, like most tools. We need to relearn ethics and from Whom that comes for why to use the tool and then learn how to use it wisely. Part of the wisdom is to use it in ways that limit exposure to risks by containing treatment to one ear, one eyeball or other limited body part until we understand its use better. And to limit its use to those few with the most to gain and either the least to lose or the poorest other options until then. Proceed cautiously to more uses as you learn. And don’t forget old wisdom. Tales like that of Icarus have been around for a long time.
