This document discusses the history and future of telecommunications networks as the traditional telephone network (PSTN) declines. It notes that in 2050, efforts will still be underway to improve security in SIP and create new open source projects. Small independent communication networks may emerge if federation between networks breaks down as the PSTN dies. Key questions are how users can maintain a global identity, how sessions can be trusted without federation, and whether networks can survive without interconnecting.
