The problem of running today’s software decades, centuries, or even millennia into the future.

In a setting of economic and infrastructural collapse, the inability to manufacture and maintain computing resources will be an enormous limitation on the continued use of technology. The concept of “rot” exists for both hardware and software, referring to a slow loss of functionality over time. Given a desire to maintain technological capability, we raise a variety of questions about technology use in such a scenario. How long will current hardware last through repair, robust construction, and good maintenance practices? What would software development and maintenance entail without today’s Internet infrastructure? What can be done to keep our software stable and usable for as long as possible in the face of viruses, storage degradation, and other threats?
