The gradual return of symmetric connectivity, which is underway today, as well as edge adoption of IPv6, could/should usher in a revitalized era of peer-to-peer and other decentralized computing models. Peer-to-peer models last thrived when connectivity was predominantly symmetric (e.g., the early days of DSL) and faded quickly as asymmetric connectivity became mainstream. I think the decline of decentralization and the rise of asymmetric connectivity are intertwined; neither necessarily caused the other, but they are correlated. One could argue asymmetric connectivity became popular because users only wanted to consume rather than share/serve. But similarly, people stopped sharing and serving because their connectivity discouraged that use case. Today, symmetric connectivity is returning, such as in the form of 1G/1G fiber connections to the home. Combine this with infinite static IP addresses, and ever rising edge compute capacity, and I think decentralization is inevitable. I won't predict the magnitude, but as a fan of decentralization, I personally hope it is at least significant.
