What of the names still known hundreds or thousands of years later? Aristotle, Confucius, Cleopatra, Mansa Musa, Siddhartha Gautama, Joan of Arc, Jesus of Nazareth. These people, or at least their legend, have permeated cultures and civilizations for dozens of generations. Why is that? Why does the memory of their lives survive past the arbitrary 100-year mark? I would argue it's because these people offered something meaningful to the world, things that had lasting impact on society, civilization, or our species as a whole. Their contribution has implicated results for centuries, and we credit them for it. They weren't entertainers or pundits or athletes. They were bringers of change, those who helped society move from zero to one on something important. Often their ideas are still relevant today, still influencing how we see the world.
This isn't to disparage journalism, sports, entertainment, or any other mechanism of society. As I mentioned before, one can choose to earn a living and find meaning outside of vocation, and I don't believe there should be judgement around that. This is simply to examine our lives through the long lens of history. And while I think this may be uncomfortable at first, it also provides a freedom for our choices. Not an escape, but a true reckoning with how we want to live our lives. We can choose to dedicate them to a cause we believe will help our species, improve the universe in some fundamental way, understanding the significance of our work is not about us or our memory but about the contribution itself... or we can accept that we'll be forgotten, and enjoy life, teach our children what we believe, and find meaning outside of "work." In a way, it's not really a choice, but a surrender to the physics of our universe, without yielding fulfilment. In the end, we as humans enjoy the freedom to choose our path of meaning.
