I wonder if a multi-block-radius arcology as dreamt of in sci-fi will ever be built. Probably would require technology allowing both building strength improvements and construction cost reductions (automation?) along with reform of the legacy skyscraper regulations described in the article. Of course massive economic price pressure and/or governmental action would be needed for such a project. It may have to piggyback off of a more critical infrastructure project, such as the support structures/legs of a space elevator (like Zalem in Battle Angel Alita).
