Because more and more people are born with genes that make their life difficult and increase their chance of death, genetics created technologies that allow to “cut” harmful genes, adding new and activate genes and deactivating those genes people already have.
DNA editing is not only a great way to keep people healthy. This can be used to help people who want to become great athletes but don’t have genes that would make them good at a particular sport. Or, people who want to become scientists but have difficulties remembering things. Of course, genes aren’t enough to become the best. Even with good genes, people would need to improve quite a bit if they wanted to become successful.
Simply put, beneficial genes are only an additional help, not 100% guaranteed results. So, even after gene alteration becomes popular, people would still need to do a lot of work.

My relative actually had IVF  via test tubes after checking the husband gene is healthy first.
He had a Sick gene from his parents and did not want to pass the same bad gene to baby.
The son is now a lovely 1 year old.
