I think writing one of the best selling books of your century is extraordinary evidence you’ve understood something deep about human nature

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.
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.
