What if you lived every human life that has ever existed on Earth?

What if you experienced every human life in history? · 5:21 · Video: TED-Ed · Watch at the source

In short: Imagine experiencing the entire span of human history by living every life consecutively. This thought experiment serves as a gateway to understanding longtermism, an ethical framework that challenges us to consider how our current actions ripple through time to affect all future generations.

The concept of longtermism suggests that we have a moral obligation to prioritize the well-being of future people. By framing existence as a series of reincarnations—from the first human to the last—the philosophy forces a radical shift in perspective. If you were destined to inhabit every life that has ever walked the planet, your current choices would no longer be isolated events but rather foundational impacts on your own future selves.

This exploration, directed by Jay Septimo, Khoo Siew May, and AIM Creative Studios, examines the weight of our legacy. It asks us to treat the collective human experience not as a series of disconnected lives, but as a continuous thread of responsibility that connects the distant past to the far-reaching future.
