From the article: “This opens the door to advertisements from fertility clinics of giving your child the best start in life with a gene-editing packet, and whether these are real advantages or perceived advantages, they would accrue disproportionately to people who are already advantaged.” Germ-line "vaccination" against common heritable diseases may go a long way in decreasing health-care costs over the long-term. My belief is that this is the first area for gene-editing. We should create legislation that allows us to separate cosmetic or "value-add" (Increased IQ, etc.) gene-editing from basic disease prevention. One thing I would like to note, however, is that the loss of common heritable diseases does not make our population, necessarily, stronger. Many disease genes have been linked to "Hybrid-vigor" type effects, in which case being a disease character makes the carrier more fit.
