Previously, Kurzgesagt attempted to explain where all the aliens are by touching on The Fermi Paradox. This time around, the video explainer comes up with some possible reasons for why we haven't found any aliens yet. We might be communicating with them wrong. They might be extinct. Maybe our technology isn't there yet. And so on.
Where are all the aliens? The universe is too big and too old, why have we not met aliens yet? Do they live in computers? Were they wiped out by an ancient super intelligence? Or are we just to primitive to understand their motives? Whatever the answer is, it is incredibly important for our own future.
