Funding be damned. No one is asking you to work your arse off Interstellar style to fund a secret program to fund humanity and get us out of here.

But it will happen - and there will be commercial starts to it - asteroid mining, with initial small numbers of support personnel up there, then maybe a few habs. Maybe it will take generations; or maybe we'll be wiped out before then. But it is either part of the inevitable march of the story of our civilisation; or there won't be a civilisation to talk about
