At our present technology and species interest, living on the Moon is much further distant than 100 years.
Considering the fact we have no techology for heavy lift, repeating orbital flights nor the interest for finacial support. Then tack on a 1/4 million mile one-way trip and the ability to erect said habitat on the Moon which not only includes lifting materials but people AND supplies AND landing them on the Moon, erecting the habitat in hostile environment with limited room for success then returning to Earth and doing it all over again and again successfully within a limited window of survivability.
We haven't even started delivering unmanned material drops or surviival supplies. Its still a huge endeavor to send a few astronauts to the ISS for low earth orbit.
PLUS, we have yet to discover a method of protection from cosmic rays and solar radiation beyond the Van Allen Belt. Outside the Earth's magnetosphere even space is hazardous to humans for an extended period of time, even with our best protection measures.
Plus, due to wild temperature extremes any material you send there would need extreme hot to cold viability. The side in sunlight cooks while the side in shadow freezes. Metals and plastics without the ability to withstand such extremes quickly stress crack and become brittle. Rivets pop, welds pop and surfaces fracture. It happens already in aircraft over time that are not exposed to such extremes.
Its a pipe dream.
I'm not saying it is impossible.
I'm saying we as a species are not able to do it in any reasonable time frame without a major technological breakthru and a change in public priority.
Right now, if the ISS were suddenly cut off from ground support. Everyone on it would die.
Personally, I think speculation is the most important part of science.
I'm sorry if you don't see the point.
