Finally! Something clicked. It took everyone on the planet dying – the end of the human race – for D.S. Moss to emotionally comprehend his own death and feel the preciousness of life. The feeling, however, isn’t all good. Now he’s forced to reconcile being part of a species that would create nuclear warheads, biowarfare, nanotechnology, artificial intelligence and more CO2 than any of the previous mass extinctions. Well, he asked for it.

In this two part episode of The Adventures of Memento Mori, D.S. Moss goes on a scientific adventure into the past, present and future of humanity to find out what will be the most likely cause of human extinction. After exploring the threats of asteroids, super volcanos, aliens and the wrath of God, D.S. Moss learns that the most probable cause of the next mass extinction - humanities extinction will be caused by either Artificial Intelligence, nuclear war or climate change. Turns out humans are the biggest threat to themselves. Are you surprised?
