Great post. In the running for your best ever. "To put a random number on it, I doubt that anything more than one-in-a-million g-factor is required to be a potential world-class genius, implying at least six thousand potential Einsteins running around today." Let's hope it's not one-in-a-hundred-billion. Because then we may never see another potential Einstein.

For the life of me, I don't understand why no one else in the intelligent, persistent-maximizing space wants to start assembly line cloning/breeding our smartest existential risk minimizers besides me (and possibly one other person, I don't know if they're public about it). If this happened in the next few years, a lot of us could benefit from the potential accelerated breakthroughs starting 25-35 years from now. I think smart, open-minded folks (Eliezer, Robin, Aubrey) need to justify to us why they're not pounding the podium on this one NOW, at least anonymously.
