You should also watch Idiocracy http://www.imdb.com/title/tt0387808/. It's a more minor movie but it shows the other side of the problem.

Gattaca shows the issues with doing designer babies.

Idiocracy shows the problems with not doing it.

You should think about what problems are worse and what ones are more likely to happen.

(sorry for the double post, how can I delete my top level post on this?)
