> So whether or not one calls for zero growth, we should plan for an eventual situation of zero growth and structure our society so this is a good outcome. But how far in the future is this? Our light cone is finite, but it has a vast amount of energy and matter. Maybe we don't get much father than the solar system, but that's still a lot more resources than the Earth. Just the sun itself is an enormous ball of energy we're barely making use of. Sure, a Type 3 civilization might find it difficult to grow much beyond it's galaxy, but it would take a while to get to that level. We don't really know where civilization might end up in the long term.
