My first reaction is to wonder what the downside of such a gene is. Perhaps there is no downside for the individuals that have it, but these individuals serve a particular purpose to the greater civilization and lack other capabilities that benefit humanity as a whole. If there is a trade-off perhaps it is not at the individual level.

Maybe it's similar to the idea that we can just eradicate mosquitos with no negative effects. Is that really true?
