IIRC, there is plenty of material available for such development without leaving our solar system, it’s just that most of it is out in the Oort Cloud. With the current tech we have this is not doable, but advances in space travel could make such things possible, over a period of millennia.
I do not personally think we will make it that long, environmental and societal collapse will end our species’ advancement first.
