Currently, we've yet to make a child with a certain hair color ASFAIK. But I imagine that's just around the corner. But how far do you think Human Engineering can go in the farther away future? Do you think it's possible to give humans gills or the ability to hold their breath for an hour. Or to give everybody genius level intelligence? Or to fly, to give mankind wings?!? Do you think someday we'll do it? I hope so, that would be an amazing future.
*sigh* I need to stop watching X-men...
