Yeah. To achieve 3% growth per year for several hundred years we have to expand beyond Earth. Beyond a few hundred years, it starts getting more difficult. I wonder how much waste heat Mars or other large bodies could absorb. Or what is the largest possible radiator we could build in space... Some fun facts I calculated while thinking about this: * 3% growth for 100 years is 20x * 3% growth for 300 years is 7,000x * 3% growth for 1,000 years is 7,000,000,000,000x
