I think that we shouldn't generally take Hollywood movies too seriously when thinking about public policy. It's heartwarming to think that the will can triumph over heart disease but in things don't usually work that way in real life.

The current lottery in genetic endowment that nature provides us is horrendously unfair. I expect that fixing problems is going to be a lot easier than creating super-human abilities so I expect that genetic modification will tend to make life much fairer for the foreseeable future.
