There's an astounding arrogance that is common among many people today. It is the assumption that generations that came before us were essentially stupid. Yet in many (most?) cases those people had more knowledge and wisdom than we do. They were constantly exercising their brains to store and retrieve information, while we only know how to ask our phones for answers.
If you took even people we call "ancients" and raised them today, put them on the shoulders of the giants we're camped out on today, I have every confidence they would do just fine. And I even wonder if the people of greatness from the past were great in part because of their struggles. Raised in our cushy environs, they would become like us, soft and drifting.
