Human race will 'split into two different species'

[albed]

Nonsense. You're just as bad as that "top scientist" with no evidence or explanation, just your pronouncement. And biotechnology certainly isn't a "social force" so you're already contradicting yourself.

Society has little or nothing to do with reproduction, it's a fairly personal choice made mostly by women imo, at least in advanced, liberal countries with birth control options. And they're still driven by animal instinct from what I can determine, so they're still selecting for looks, health, wealth, etc. even when it's from a sperm bank. So I really don't see any "social" forces at work. But feel free to elaborate.
