What can cause and count as human civilization collapse;
AGI: Artificial intelligence could turn against human interests.
Ecological Collapse: Climate change could radically change Earth's populations.
Nuclear War
Global Pandemic
Widespread Economic Collapse
Self-sustaining communities beyond Earth, whether on other planets, moons, asteroids or in artificial space habitats will count as multi-planetary species status. These communities should be able to sustain themselves completely independent of Earth. A measure could be if Earth is annihilated those communities should be able to exist comfortably.
@AdamDyer Its not about winning or losing its about our perception of future of humanity. We all have our ideas of likelihood of things. But aggregated, you get a fuller picture. I think thats one important aspect of this platform.
@Devansh I provided a list of risks; and made AI fill in the descriptions. so yeah; sorry it is AI-generated. but not low-content. 5 risks listed are indeed the biggest threats to human civilization.
@SimonFillat Multiplanetary is really a placeholder. It doesn't have to be on a planet. Its a human colony able to sustain itself without the need for anything from earth. There could be still trade, but if trade is ceased they should be able to recover from that without significant impact like widespread starvation etc.
