There has been one persistent theme through all Axis propaganda. This theme has been that Americans are admittedly rich, that Americans have considerable industrial power - but that Americans are soft and decadent, that they cannot and will not unite and work and fight. . . . Let them tell that to the Marines!
Yes, we know more than ever before, and it's a wonder that we get to inhabit a world full of driverless cars and 3D printers. But that doesn't mean that we know any more about the essential things in life - love, faith, death - and it would be dangerous to assume we did. The only thing that gets us through sometimes is a proper, humbled sense that we don't have a clue, we can't be sure what's going to happen next and life will always be much larger than our ideas of it.
