That Spartacus clip posted earlier is powerful because it strikes at the heart of a human’s desire to be free.

If I had to pick between two paths:
1) Genus Homo can continue for another 300,000 years if our population becomes managed, like a herd of cattle, with selective breeding (genetic engineering) and culling, with decisions about who gets to live and when people get to die, though the engineering efforts of a subset of specialists empowered to rule; and
2) we just let ourselves go extinct;

… I think the second choice is the one I would make.
