Organs can now be grown!

[Chaerophon]

The world's population is in no danger of heading into negative growth. Is this a necessity or a luxury? From an evolutionary perspective, does this not aid and abet watering down the special gene pool? If dealing with a congenital ailment, what is the good of cloning bad tissue? Of course, it can't hurt to try and reboot the bladder, as it were.

I know you're playing devil's advocate here, but I don't think that we need to take evolution as a moral imperative... :)

Anyways, my two cents? Wonderful news! I do worry about the ramifications that Munk mentioned, re: "luxury surgery", but assuming that we don't develop a new "overclass" of immortals, I think that saving people from the ravages of cancer, disease, and defects will always be a good thing.
