The concept of gene editing on an ethical level has the issue where it gets very close to eugenics, something generally thought to be unethical (and I agree). While its currently being talked about getting used to remove genetic illnesses or strengthen the child’s resistances to things like HIV, the technology can presumably be used for much more. While some people may find it unethical to edit genes at all and consider the ethical course of action to be letting the child be born with zero intervention, many others find that to be perfectly ethical as if it is successful it will presumably improve the child’s quality of life drastically. But what happens when you go farther than that and start identifying any “undesirable” trait and editing them out? The ethical implications of this are far more dubious. Another issue that I hadn’t considered before reading the article was that we have no way to truly know the long term effects of this without observing them for ourselves, so children will need to have their genes edited, be born, and live their lives for us to know how they will develop long term. Even in the best case scenario where there are zero complications and they live healthy, happy lives, they are still essentially lab rats, put into this world with zero clue of the consequences. In the worst case scenario where the children are horribly deformed or have any other number of health defects, the people who edited their genes directly put them in that situation and were fully aware that this could be the result. I think most people would have a hard time finding this ethical.
