Let us not think in the authoritarian terms of some individuals genetically engineering the characteristics of others. Instead, let us think in the egalitarian terms of each individual genetically re-engineering herself/himself according as s(he) pleases. What is being suggested here is that in the distant future, by means of in vivo genetic transformation techniques effected with recombinant DNA or some other biotechnological tool(s), it will be possible for any person (or other kind of organism) to be an introverted, academically-oriented, purple-haired, orange-eyed, 10 foot tall white male with an IQ of 160 on any given day and a party-going, humorous, green-haired, green-eyed, three foot tall green female with an IQ of 200 on the next day. Stated in more general terms, it will become possible for each one of us (that is, anyone alive during the future era in question) to be whatever we want to be whenever we want to be.
