Although you could see it as reproducing this human (breeding, eugenics) you could also look at it as discovery and training. Sort of like being able to spot a really great runner at age 5 and getting them to the Olympics by age 18, etc.

I think if we can understand (since it probably isn't IQ) the "real" reason this person has such above-average abilities then we can find ways to test for it and help other people with these abilities develop fuller potential, and hopefully humanity gets something back - in both the arts and sciences.
