Agreed. This is the crux of the problem: if we're worrying about this leading to an "underclass"... does anyone think its illegality will prevent the ultra-wealthy from funding this technology?

And who will be overseeing the research? If it must be conducted in the dark and on a budget, does anyone doubt that human experimentation will take place?

No thanks.

Ethical or not, the cat is out of the bag and the only way is forward.
