Context of personal computer is very interesting. My bet here would be that once you can talk to other people personal context maybe inside the organisation you can cut many meetings.
And more science fiction, if you connect all different minds together and combine all knowledge accumulated from people and allow bots to talk to each and create new pieces of information by collaboration this could lead to a distributed learning era
Counter argument would be that people are on average mid IQ and not much of the greatest work could be produced by combining mid IQ people together.
But probably throwing an experiment in some big AI lab or some big corporation could be a very interesting experiment to see an outcome of. Maybe it will learn ineficincies, or let people proactively communicate with each other.
