I obviously agree that in its current form this therapy has no potential for use as a means of enhancement (at least if we define enhancement as deviation above normal human baseline).
But it’s worth pointing out that the chemotherapy step of the treatment was only necessary because ANY remaining sickle-cell carrying stem cells would continue to produce misshapen red blood cells which cause all of the symptoms and problems associated with the disease.
Other conditions are not all like that: going from no cells having a copy of some particular variant to SOME cells having a copy would still produce a positive effect.
The real reason I think somatic cell editing is unlikely to produce any large enhancements any time in the next 50 years is because you have to edit an ungodly number of cells all over the body to have an effect, and some of the modified genes won’t do anything because they’re only active during the developmental phase of a person’s lifespan.
