there's two ways to face this situation, the pessimistic one is to just die. Futuristic sci-fi stories usually have endangered human or even human extinction aspect in there, with / without harsh climate and / or war / conflict. The optimistic? Hold out until the chance come. In thousands (millions) years of human civilization, not a single civilization can stay eternal. That kind of civilization will perish too, if not the humanity to perish first, especially because Murphy's law (if something can go wrong, it will, and usually at the worst time). And IMO that kind of civilization will still have a long way to arrive, and we're more likely already dead before it arrive. Because that one Murphy's law, and limited resources for automation. In an area where infrastructure is not yet sufficient, usually human are the best to handle the job.
