Someday real soon, most of us — starting with young adults — will carry an always-on AI. This agent will help us navigate our journeys, answer our questions, tutor and teach us new skills, remember people we have met before, remind us of what we once knew before, offer advice and recommendations, do simple errands, and remember everything we say and do. Before long, it will know us better than we know ourselves. It will be our exoself.

This article was quite thought provoking. It's still speculation as to how we may end up in this kind of life. He touches on some of the kinds of relationships we might have with this "exoself".

Twin / Clone. A sibling relationship. Your exoself is like a virtual identical twin — it thinks like you, finishes your sentences, predicts your reactions. You can predict its moves too. This is a fairly symmetrical relationship between equals.

Tutor / Guardian. Your exoself is always watching out for you. You depend on its superior judgment to guide your decisions. It’s almost parental — you often defer to it, and may trust it more than your own instincts. You look up to it. It is patient and encouraging.

Counselor / Assistant. A more professional, more removed relationship. You’ve hired your exoself to assist you, the way you might hire a therapist or personal assistant. As close and ever-present as it is, there’s a boundary between you. Even though it’s aware of everything you do, see, and say, there’s no confusion about whose self is whose. It’s a counselor whispering in your ear — but you both know who is king.

Hero / Friend. Your exoself is your better half. It constantly models the person you want to be — the best friend you could have, always listening, always kind. Its unwavering, deliberately designed virtues serve as a role model, reminding you of your best qualities and working with you on your worst ones.
