The one real worry I have about scientists is that they're too personally invested.

I have this same worry about a lot of bioethicists. Their whole shtick is telling scientists what they are and aren't allowed to do, and getting public support for their own actions. That's a recipe for fearmongering and being more restrictive than they should be in order to justify their own existence.

Obviously there are ethical decisions to be made in the field of biology, and it would probably be nice to have people who specialize in hashing out those issues, but the way the system is being set up seems dangerously dependent on -- and compliant to -- unfounded public fears.
