>>158570I wish some billionaire would just build an underwater settlement already. I got a taste of living like that as a kid, and thought we'd have whole colonies by now. It's incredibly fun to live amphibiously like that.
It's so much cheaper (by a factor of about a thousand, as quantified by cubic feet of habitable volume) than putting manned structures in space that any individual billionaire could easily build something like in the picture that would house hundreds, without putting a serious dent in his bank account.
