I don’t the modularity is necessarily lost with a mega structure like this- interior remodeling of office, residential, and space happens all the time. As for the updating- East St. Louis had extremely out dated housing stuck in the 1980s when this was proposed and it hasn’t gotten better AFAIK. I think the real problem (outside the aforementioned capital outlay) lies in the issues with the interface with the rest of the world/community. The Arcology is just to self contained and reality isn’t. It’s often hard enough to find locations within a current large office building or complex, it would be even harder inside this concept. That’s really going to limit the retail and service industry inside a mega structure like this. The circle shape is also a problem- circles don’t pack well, so there is a natural stand off are between the Arcology and the rest of the community. Integrating the internal and external transport networks and infrastructure would be darn near impossible.
