It's possible what you describe could be achieved by AI compositing. I.e. The AI creates a central view of what it believes is the most relevant info for your current task. This doesn't require any changes to the programs themselves.

Longer term, I think voice + AI assistants can help with this. In programming speak, our UX will become more declarative and less imperative. Combined with AR/VR interfaces, this will see a big improvement in productivity.
