AI devices will assist us for everything we need to know. We won't need to spend time learning and memorising because everything we want to know will be accessible when we need it, where we need it.
Scientific, medical, legal advices, all sort of expertise will be delivered by our portable AI device that we will carry around everywhere with us. Whatever the field, the best expert will be an AI device as it will have the expertise of all the experts combined.
