Of course not. Cultures which reverence tradition over modernity will always lag behind the rest of us.
Even here in America there are certain regions where superstition has created a populace that is ignorant, degraded and poor.
And when does your 'modernity' turn into tradition? lol
after our descendents learn to live better still
What is 'better'? That term is completely subjective... you're assuming that things get 'better' just because time passes, how do you reconcile that? Humanity is no better now than it was 1,000 years ago. There's still hate, murder, rape, war, greed, jealousy, and on and on... We are no better now than the people that came before us, as a matter of fact, I'd say we may be worse because we rationalize evil by saying that it's 'better'.
