Ever since the time of Darwin, science has been gradually revealing (to those with their eyes open) that we were created as part of a giant game of passing information into the future.
Ever since thousands of years before Darwin, the most creative human beings have been engaged in information games other than the biological one, including the game of passing information into the future. They have done this through creating and participating in institutions, writing literature, and inventing maths. (They have also done this through writing radio jingles, copying and sending chain letters, and breeding pigeons.)
When the game of making human babies did not have a good opt-out (i.e., prior to around 1970 C.E.), participation in the wider information games was largely instrumental for better playing the breeding game. But with good ways to opt out of breeding new humans, the original game - the game of breeding to pass some of one's genetic information into the future - is coming to be recognized as a small, rather pathetic subset of the total space of information games.
Only the least creative and least intelligent will continue to play the original game, with its massive costs and limited returns. Those who can't think of any more interesting information game to play will be the parents of future biological humans.
But lamenting this is like lamenting brain drain from print newspapers to electronic media: missing the point, because that's no longer where the interesting information is being created and passed around.
