Everyone has a time machine. Everyone is a time machine. It’s just that most people’s machines are broken. The strangest and hardest kind of time travel is the unaided kind. People get stuck, people get looped. People get trapped. But we are all time machines. We are all perfectly engineered time machines, technologically equipped to allow the inside user, the traveler riding inside each of us, to experience time travel, and loss, and understanding. We are universal time machines manufactured to the most exacting specifications possible. Every single one of us.
– Charles Yu, How To Live Safely in a Science Fiction Universe
But we are all time machines.
