gollark: Maybe.
gollark: That won't technically operate *forever* without harvesting more stuff.
gollark: Firstly, technological progress allows more efficient use of the existing limited resources.Secondly, technological progress allows more efficient extraction of more, as well as access to more in e.g. sspæceë.Thirdly, unless perfect recycling exists somehow, I don't think there's an actual alternative beyond slowly scaling down humanity and dying out or something. Or maybe regressing living standards.
