> Humans can form 'tribes', in the loosest sense of the word possible, based on genetics, but we also form tribes based on similar beliefs, values and interests - for example, Hacker News :)

I agree with this, and I'm glad we do. But I've posted the "let's harvest clones for organs" idea numerous times on HN -- a community where many of us are on somewhat of a similar wavelength. It's usually met with a lot of vitriol and disgust.

That's one of the nice things about this. It would give us an organismal research platform where we could replicate experiments. No more animal studies, imperfect chimera systems, or molecular experiments we can't scale up. We'd have a perfect test bed for investigating almost everything that ails us.
