Theres actually a shortage of sand which is crucial to construction we likely won't literally run out of raw materials to mine but it'll become increasingly difficult and expensive not to mention environmentally deleterious where looking to the moon and beyond would seem like a pretty good idea within the next 25-30 years or so this is what we should be focusing on instead of colonies and manned spaced missions or whatever stupid shit elon musk and his cult following want to do
I’m not sure I can accept that manned space missions are more implausible than bringing back enough mass of a granular material to be useful for construction on a worldwide scale. FROM SPACE.
We’d have to build one of those giant electromagnetic space coilguns/tracks that gets costs down to $50/kg - if you launch 35 tons to orbit every three hours.
And TBQF it just isn’t worth the money right now unless you want to build a Bernal Sphere as a backup in case of nuclear war/etc.
