@graydon @cstross I am intrigued by the idea of humans as eusocial organisms — like ants. Not the first time I’ve encountered the idea, but this phrasing puts it in a new light.
A few years ago, I saw an interview with an atheist who was an enthusiast for extreme sports. He said dying did not concern him, it just meant that his consciousness would end and he would return to the Earth. I was watching with someone who is a believer in spirituality and New Age beliefs — she said she believes the same thing.
We are part of a larger whole, and the whole continues when we cease. No man is an island.
Also: The Olduvia Theory seems like clever and intriguing science fiction, but basically baloney. Far too much speculation and back-of-the-envelope calculation.
I can imagine the human race being forced to rely on far fewer resources, and I can — terribly! — imagine a resulting mass death event leaving only 1% of today’s population. But I can’t imagine that we’d simply roll back 10,000 years of civilization.
