There are many ideas and no definite proof. I like the idea that species either try to reach the stars and fail because it costs too much energy, or they find a sustainable lifestyle and not leave their home planet as Dr. Fatima pointed out in a good video
Nice, thanks. I’m of the opinion that any form of civilisation is doomed in about 200 Earth years’ equivalent past their industrial revolution. It is a bit crude, but I will say: so far 100% of the cases I’m analysing have collapse as an expected outcome.
What even makes you think the industrial revolution is a given? It happened exactly once at earth. Also: We are not doomed. It is easier to imagine the end of the world than the end of capitalism but both are possible outcomes
