Tom,
you're not wrong, but don't forget that new technologies emerge all the time. They have just started to experiment on growing livers from stem cells, and if you can master that, growing something simple like dick should be easy.
That being said, you reminded me of my first thought when I learned of the invention of Viagra. I thought (and this is no joke) that this should help all those endangered species that are used for boner voodoo; since Viagra actually works why would people still use overpriced powdered Elephant dick or w/e?
Years later I find out they still use the voodoo, just
together with Viagra, and are now more convinced than ever the stuff works.
So I might be overly optimistic here.
