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.
I wanted to disagree but I really miss IRC internet. Saving everything we ever said online was a mistake. We need to focus on ephemeral chat making a comeback.
Saving logs has been essential for work, in the past, because we were always to write real documentation when necessary. Mind you, this was local to our machine.
But on IRC you had your own log, and sometimes the server made the full logs public. It was just cumbersome to access. What I said and you said in my presets was still logged.
It's a muddy middle ground where neither you are I are satisfied. Far from perfect.
