Cancer-schmancer - I want that 10-foot long schlong! Someday we'll all have a full head of thick luxuriant hair, huge penises for men and giant breasts for women, have big bulging muscles and zero-percent body fat, a permanent tan (but everyone will be "white"), and abundant self-esteem because of our shallow physical perfection.
Of course, at the same time we will be hopelessly sociologically and psychologically damaged, completely uneducated, and be eaten alive by cancer and horrible neurological diseases. Because there's no money in dealing with any of that stuff. And it's tough to put together a sexy marketing campaign for a cure for cancer.
Given the choice of looking good and having great, long duration empty sex, or living longer, most people would say "screw living longer - I want to keep a hardon for six-to-eight hours".
But the MAIN reason the genome will be developed and exploited is BRAINLESS MUTANT SOLDIERS WITH NO SELF-AWARENESS. Politicians will like the idea of having a massive military force to wield for their own corrupt ends, without ever having to resort to a draft (which might hurt re-election chances). BRAINLESS MUTANT SOLDIERS WITH NO SELF-AWARENESS are on the way!
