This kind of thing shouldn’t be thought of as a “vision”, which sounds like it needs to be at least a plausible prediction, but as a kind of exploratory engineering. The latter is something that isn’t currently feasible to accomplish, would become possible to do with greater technological power, but probably will never be a good idea to actually do this way, because there would be other (even more worthwhile) things to do once the requisite technological power is available.
