That we really are living in unprecedented times. If you look any of a number of indices, things really starting changing for humankind as a whole about 150 years ago. A lot of this I knew before, but didn't grasp how many things changed, how dramatically, and how recently. It kind of is like living through the onset of the dawn of agriculture or something, but compressed into 150-200 years. I think people (myself included) aren't aware of how much uncertainty we're facing as a civilization. I don't actually mean that positively or negatively, just blew my mind.
