The great debate between the moderns and those who still cleave to classical philosophy is about the perfectability of man. The moderns think that as a species we're getting better, evolving, if you will, via politics and science. The classicists believe that man's perennial problems are fundamental and therefore permanent because they're in our nature.
So, when modern science evolves to the point where we no longer need intercourse to produce babies---oh, wait, it already has---will we forget how to do the nasty?
Not so far, if you read the tabloids, but it does give one pause and a shudder, especially if he's of the soon-to-be-obsolete male persuasion. Although certain clinics provide a receptacle and a turkey baster to salvage the proceeds of Onanism, in the forseeable future it looks like science will be able to make sperms out of eggs. The perfectable hive won't need us as drones or even Onanists, and all we'll be good for is philosophizing, starting wars, and leaving our underwear on the bathroom floor.
The Abolition of Man is what another fellow called it, in a different context but not all that different. In another generation or a hundred from now, it looks like my species would be laying me off.
(Oh well, enough of this, I'm out. A couple of games I really want to watch are coming on and I have to hunt down the remote so I can toggle back and forth. A man's gotta do what a man's gotta do. It's his nature.)
