I believe that thanks to such technologies, changes in the DNA at the initial stages of development, other interventions are more likely to be more useful than moral problems. First of all, it is possible to avoid quite a lot of diseases (for example, Down's syndrome) by such interference, it is also possible to get rid of many other diseases and find out at what period of their life they will appear and progress. You know the proverb: "who is warned - he is armed." We must look to the future more confidently and, therefore, should develop in all spheres, and most importantly it is that such technology should be accessible to disadvantaged people, from the fact that the benefits from this will be much greater than if it is a privilege of the rich.
This is a serious topic for discussion, so the final decision should be made by serious people, the entire world community of scientists ...
Thank you for raising such topics, it's very interesting
