I'm similarly optimistic that outcome is possible, maybe even probable, but I'm not excited for it. When it comes to population and the future, the question is less whether we can survive, the question is what kind of world is consistent with 20Bn people? Or 1 Trillion people?

If you value open space, wild places, other species' existence, bucolic lifestyles, or other non-techno sci fi outcomes, that's a scary thought. Maybe we will all move to space and keep earth as a re-wilded paradise for vacationing and research. Or maybe future generations won't care about any of that and will densely cover the whole planet, snuffing out anything that came before.
