If you can consider your own identity as a continuously revised story you tell yourself (and others) about yourself — or an ongoing dialogue with yourself about who you are - then it would be useful for this key management hardware to mirror that dialogue: what am I saying about myself to the outside world? What bits of information are critical? What info doesn’t reflect my current perception of myself and how can I correct it? What info has been encrypted in a way that may become obsolete soon and needs to be migrated? Basically a personal, offline, conversational identity trackerbot.
