If this is ultimately verified it will mark a turning point in gene editing. Notwithstanding all the condemnation, no country will want to be "left behind" so to speak and a race to the bottom will ensue. I expect that initially gene editing will be used for viability purposes but will inevitably spread to other "desirable" characteristics such as physical traits and mental ability.

Depends on how risky it is. CRISPR is pretty messy in a "don't do it to anything you can't afford to lose" way from what I heard given outright deaths in subjects from peripheral damage. Fine with plants or livestock but a damn good reason not to apply it to humans cavalierly.

It is probably preferable to certain severe genetic issues but that should rightfully give pause.
