We cherry pick what we look back on. We don't look back on the average life from those days. What if the Middle Ages didn't happen for a lot of progress? Would we be like in the stars right now, having defeated aging and progress doesn't depend on the calendar? People have to make it happen. And if for a while people don't make it happen or block it, it's not going to happen. So we have to do our best right now for the future, for our kids.
