I wasn't saying we were headed toward ecuminopolis status. We're not. Our global population is projected to level out soon, and as more countries teach developed status, it will probably drop slightly.
And yes, my power estimate for the ecuminopolis we aren't going to create was low. But if most people's journeys are taken by high-efficiency electric trains with hundreds of people in them rather than cars with only one, and people consume efficient plant-based protein rather than meat, the per capita power burn will drop. We might still be in the exawatt range instead of the petawatt, but the sun, planetary core, and Jovian H Reserves will provide more than adequate juice.
