Seveneves, by Neil Stephenson, discusses the human penchant for self-destruction much better then I can in an HN comment, it is worth a read. In short, though, we cannot, unfortunately, escape our humanity, and pretending we don’t take it with us wherever we go is wishful thinking. As a group, we are ruled by incredibly base instincts that no longer apply to our situation, but they still largely determine our trajectory.
You’ve clearly read the book, I am curious what would drive you to make such an obviously incomplete representation of the story. Being edgy? Contrarian for contrarian’s sake? Since you offer no additional context besides a vague (and uninteresting) insinuation that im somehow wrong, I suspect you are just trolling, smegger001
It also has no predictive value given the nature of catastrophic threats continues to evolve rapidly in quantity and quality, and the elements of past threats (the cold war -> nuclear war), continue to be threats (autocratic regimes -> fighting or planning wars that could become existential to their leaders -> nuclear war).
The more widely accessible a technology becomes, the more damage a single person or faction can do, and therefore the probability of someone causing mayhem tends to 1. And it's basically always less effort to destroy something than (re)create it
We can hope defensive counterparts to all these risks develop at a greater rate, but I don't think that's a given at all
Also remember that from a SETI/Fermi/Great Filter perspective it doesn't matter whether the species completely kills itself off. It could instead just repeatedly reset itself to steam age technology, and therefore never be stable enough for long enough to become seriously spacefaring
Have you not been paying attention to the news? We have a major nuclear power constantly threatening nuclear war, and several very likely conflicts between major nuclear powers.
