You do have a personal knowledge management base, it’s all your friends and coworkers :) I’ve heard this concept described as the “external brain”. If I don’t talk about something or write it down, it’s more likely than not getting flushed out of my brain. My friends or calendar app or sparingly few notes will be there to remind me if it’s actually important! I only write to make/check-in on longer term plans
