This seems like as good opportunity as any other to remind that the previously published study that those gene-edited babies will have shorter life expectancy, that was used to bash He Jiankui previously was retracted [0]. It almost looks like some scientists are envious of him and scramble to find something to use against him. There are risks to many medical procedures and only time will show if these are more or less serious. That said, I don't think that attempting to grant immunity to disease you might never encounter and is possible to be well treated (if not cured) nowadays was a right reason for first human gene edit. If it fixed a single gene disorder which would allow some parents to have their own healthy biological child, it would be certainly more palatable.
