Future Pros & Cons of Stem Cell Research

This is one subject that the movies can teach us about. Ethics is not as much an issue as what it could lead to in the future. My favorite quote from Jurassic Park was made by Ian Malcom (Jeff Goldblum), "Your scientists were so preoccupied with whether or not they could, that they didn't think about whether they should." If this research continues, I would like to see strict regulations to help avoid scary consequences seen in movies like "6th Day". The only reason I can't commit to a decision on this issue...is that it's so much easier to say "no" when I do not suffer from the (in some cases) terminal conditions that the research is supposed to alleviate.
