Because I prefer online conversations to work like IRL ones: Ephemeral. Sure each individual might keep their own log if they want but the server itself doesn’t and setting aside all the issues with modern datasets being used for training all sorts of algorithms, just the concept of stepping into a digital room without all the baggage of the last twenty hours of conversation is _mentally refreshing_. It also changes people’s behaviour for the better IME.

Saving logs is gross, chats should be ephemeral. In any case there's HistServ and IRCv3 /chathistory nowadays, so if you really want it you can have it.

That all the minute garbage everyone posts is preserved forever in an unfiltered state I think is a root cause of the mental degradation that results from using Discord: kids don't have anywhere to 'post into the void' anymore. Preserving past events and relationships through oral history as opposed to a big monolithic search engine entails a far more human element to IRC.
