Hardware which just manages keys — not being a web browser, not playing Angry Avians, not making phone calls — is likely to be necessary because operating system security sucks and is not likely to get better soon unless we go back to Object Capabilities or equivalent distrust-based systems.
Tell Me Who You Are

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.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
