Extrapolation is an inevitable consequence of overthink.
Anticipatory future think, based on our { or others } experienced based knowledge is fine and smart to do.
Many people do this in fields of science sociology, economics etc. It is called seeing a trend toward this or that in future, and then anticipating our needs for those future developments. Fuller called it anticipartory design science in 40's, 50's and 60's etc, wherein humanity would design more and more effective and effiency technologies to in preparation for increasing population on a planet with finite resources that, includes a finite sun.
Elon Musks largest rocket ever is in preparation of humanities growing population to have other place to live. I think his dreams are overthink and only adds to degradation of our atmosphere from the fuels used to propel rockets into space further and further.
If humanity put as much money, time and effort into ecologically sustainably livingdry --instead of weaponry--- and manager or population in regards to what our finite planet can reasonably give us without our destroying the integrity of the ecosystems resources, then I'm all for that kind of overthink, rather than weaponry and thinking Mars is the most reliable, anticipatory fore front for future of humanity.

It appears sidwalker has run away again---back flipped out of there--- from questions posed to him in the what is space and time thread.
What I see happening, is less and less farm land and more and more progressive development growth every where ive every lived, visited and seen on tv and elsewwere. It is sort of like Issac Asimov's book the Foundation, where the main planet Trantor was buildings and roads and there food came from other planets if I recall correctly.
Aaimov looked at treand an extrapolated them into SF books. There is the one were no people actually meet and speak physically to each other, and to so is considered very bad ettiquette/taste to do so. Only by tv screen is truly acceptable forms of communication.
