Over history there has always been competition between progressivism and conservatism. Progressivism has always lead to more advanced technological development, but led also to nihilism and dying off due to losing purpose and goals. Conservatism is the opposite. It stifles technological development but leads more to happiness and fulfillment by having instinctive goals that have always worked in making people happy over time.
I don't believe one should exclude the other. We should learn from both.
