Gopher runs on top of the internet, so that solves nothing. Finger is… more or less useless in this context.
You would need a whole new physical layer, and maybe replacement for the TCP and IP protocols. The later is probably doable, the former will struggle unless/until there are lots of users with the new hardware.









Reddis is an in memory cache. Your data will definitely get deleted from Reddis once the amount stored increases or even simply restarting the service. You need proper persistent storage as well so anything that’s not in the cache can still be retrieved, albeit slower. Personally, I think NoSQL is overhyped and would recommend Postgres instead, unless your application has some very specific requirements.
