I think so too. It is not only the task of replacing ideas, but in actuality it is the replacing of people that drives change. New ideas take root in young minds the most, and in old minds the least. Renewal of the population is also a renewal of the ideas that comes with them.

I think this is why everything goes downhill so fast currently: the boomers are still clinging to power, and i don’t think humanity has ever had a generation that was this persistent at keeping the younger generations from replacing them in their positions. These older people do not have the mental or emotional learning capacity left to keep up with social development, and lash out in every possible direction.
