Apparently, the technology has come far enough that scientist can edit your current genes and these changes will persist to your offspring. Currently, I believe editing your own genes to gain an advantage is illegal according to WADA rules but there is nothing illegal about it elsewhere. I would be very interested in getting my genes edited to become super human and super intelligent, WADA be damned.
And then my offspring would have my new super human traits and could compete under WADA rules because they would then be "natural". I think gene editing will massively change society and the course of evolution. Scary stuff. Makes the Nike VaporFly 4% spring shoes a minor footnote.
