Unless I’m overlooking something, that paper doesn’t go into details, to say it extremely mildly. As far as I can tell, they only say “the first aerial space colony floats free and can be sold and inhabited”. And as I said, the whole paper is highly optimistic. They’re suggesting huge space colonies (“the terraformed Venus is unlikely to be fully occupied until the population of the space colonies reaches ~3×10¹⁰”. That’s about four times the current population of earth) I think I’m not alone in not seeing us put “several small space colonies” in the orbit of Venus and construct “a heavy orbital ring around Venus” ten years after we started planning. I guess they extrapolated exponential growth of everything imaginable.
