Editing the genotype on-the-run when? It's useless to live if you cannot edit your default skin pack like you would a Saints Row character. I would modify mine, utilizing the CRISPR meme or its future equivalent (micro"CRISPR"?). If I were the president first I would declare all known countries United States of America (51st state) so there are no more wars and then employ only the finest minds Earth has to offer towards making genoswapping real.
