An AI assistant in an office would be much more helpful if it worked like a person. 1 person. 

For example I get an update from a client. I tell the AI that client X want to meet on this day.

Rather than each person in a company has their own assistant, it would be amazing if it was everyone's assistant. 

So if someone else asks it, when does client X wants to meet, it will respond with Tkay told me client X wants to meet on day/time. 

This central AI will become a data dump. instead of me telling everyone involved. I can just tell the AI. instead of asking people what's the latest, I can just ask the AI.
