Far-fetched projects like the ones discussed in the article have always piqued my imagination. As the article semi-mentions, we may at some point be forced into geoengineering and other "megascale" projects (see [0] for superconducting rings to boost Earth's magnetic field as it flips). Maybe it's just overconfidence in humanity, but I can't help but believe that we are capable of such feats if sufficiently motivated and able to work together on the required scales.
