“I think part of what scares me about the end of humanity is the end of those memories. I believe that if a tree falls in the woods and no one is there to hear it, it does make a sound. But if no one is around to play Billie Holiday records, those songs really won't make a sound anymore. We've caused a lot of suffering, but we've also caused much else.

I know the world will survive us—and in some ways, it will be more alive. More birdsong. More creatures roaming around. More plants cracking through our pavement, rewilding the planet we terraformed. I imagine coyotes sleeping in the ruins of the homes we built. I imagine our plastic still washing up on beaches hundreds of years after the last of us is gone. I imagine moths, having no artificial lights toward which to fly, turning back to the moon.

There is some comfort for me in knowing that life will go on even when we don't. But I would argue that when our light goes out, it will be Earth's greatest tragedy, because while I know humans are prone to grandiosity, I also think we are by far the most interesting thing that ever happened on Earth.

It's easy to forget how wondrous humans are, how strange and lovely.”
