What would a truly useful AI personal assistant look like to you?

Yes, we have alexa, siri and google assistant. They all do cool stuff. I can check the weather, know my agenda for the day, and get a joke told. Some of these are somewhat useful, others a cool stuff to show or try one time. I feel a truly useful personal assistant is not yet here (am I wrong? please share projects I may not know about). This is a field where I have a lot of personal interest and have been brainstorming some ideas. I'm very curious to pick your brains too and know from the HN crowd what would a truly useful personal assistant based on AI look like? What would be able to do that you can't ask alexa or siri? I'm always reminded of the next-level AI in the movie Her, and how the AI manages email and is able to naturally respond and carry out tasks. I think a personal assistant is, by definition, aware of all the important things in your life. An integration with every significant email box, calendar, note taking app, etc... would be a significant part of its "wisdom" and ability to truly help out. What kind of dialogs do you dream of having with a digital personal assistant? How would your day be easier with it available in your pocket?
