I think writing one of the best selling books of your century is extraordinary evidence you’ve understood something deep about human nature
Why do you think that? Many best selling books are worthless in rationally understanding human nature. Best selling positively correlating with good rationality would be an unlikely coincidence unless you have some good explanation.
For example, LW or SSC have been way more enlightening to me than Tolkien's stereotypical conservatism wrapped in rationalized justifications. But sure, that could just be me, you do you.
At this point, looking up to Tolkien seems like a likely result of the Halo Effect. His quotes make him seem way too overconfident in his philosophically dubious worldviews. I think I have a lot more respect for any random rationalist blogger than one who is that sure of himself but obviously wrong in some examples that are clear to us.
This theory also generates the prediction that being ungenerous to one's own kin should be attractive
Isn't that what makes "Romeo and Juliet"-like stories "romantic"? When one forsakes one's own genetic clan to elope with the mate, it signals extreme devotion to the mate and is therefore attractive.
In this comment, I merely want to focus on using the Challenger Disaster Reaction example of market capabilities. I think it's a bad example.
I think it's basically a very interesting story that would be good to tell people at a party or in a TED talk to introduce people to the idea of prediction markets by using an obviously extreme example.
I think it is a mistake to confuse good storytelling with good empirical evidence. I don't think it's valuable empirical evidence about the market being able to make these kinds of predictions.
Perhaps it will soon be the most Effective Altruism to raise your own superbabies. You're creating the next best thing to friendly AGI, in a context where the rest of the world is neglecting this low-hanging fruit. You could shape the first generation of smarter-than-unedited-human intelligence.
