Did Ancient Biotech Create "Nephilim"? Will Modern Science Bring Them Again?

From American Chronicle:

In his book 'Life, Liberty and the Defense of Dignity: The Challenges of Bioethics', the former chairman of the President's Council on Bioethics, Leon Kass provided a status report on where we stand today regarding transhumanism. He warned in the introduction that 'Human nature itself lies on the operating table, ready for alteration, for eugenic and psychic 'enhancement,' for wholesale redesign. In leading laboratories, academic and industrial, new creators are confidently amassing their powers and quietly honing their skills, while on the street their evangelists are zealously prophesying a posthuman future. For anyone who cares about preserving our humanity, the time has come for paying attention'.
