I think we can agree on what I said in the grandparent: the pope would be the biggest one-person schelling point, and it's not a good choice for initial dynamic.

Actually it might not be that bad. The theology of the body thing they have going might however mess up transhumanist aspirations I have and that would suck. But otherwise I expect a world mostly free of disease and poverty with much longer (but perhaps finite) lifespans where Western traditional values are given a boost.

That's pretty close to utopia when considering most other outcomes. Certainly it would be a more pleasant place to live than Robin Hansons em world.
