How do we build knowledge systems that outlive the cloud?

So many people use Google Drive, Box, Dropbox, OneDrive, etc., to store knowledge for corporations and private individuals. These systems are “free” and widely accessible. But these platforms have the ability to kill access whether by intention or system failure. I know I’m preaching to the choir here.

Is anyone here thinking about infrastructure fragility, decentralized systems, and local archives, all while promoting these concepts within their own real life communities? Are any of you having in-person conversations about offline-first knowledge repositories?
