I highly doubt that liberals will ever die out. I'm all for it to distinguish where liberalism, and where permissiveness. We have reached the point that when North Korea threatens the us, many Americans are afraid to fight. We constantly hear calls to solve peacefully the problem.
You know word "liberal" has quite different meaning from 100 years ago
by our current standarts the liberals of old would be conservatives today, while liberals of today would be called bolsheviks by liberals of old. So, you are completely correct, drive for innovation and change will not die out as it is inherent part of human nature.Secular cultists, who see themselves above laws of nature will die out, however. Narcissism cannot defeat God and social engineering cannot defeat Nature.
What we call "liberalism" in 21st century is not future, it is graveyard headstone to evolutionary dead end. Fertility rates are just reflection of that.
