Hal will not know who you are, and you won't know who Hal is. What you can know is that each Hal is a human, with their life of knowledge and experience, each of whom are the best on what they do and is assigned to you based on similar interests and tastes. Each Hal gets compensated for every thoughtful session they share with you.
"Hal in 5 years could be an AI that can move between systems to reach you and inevitably watch and learn your little habits and almost rethink you wishes or thoughts. I do think this is the future".
