True, but what if the pen wrote everything for you and even turned your notes into tasks that got done automatically?

Personally, I don't find that use case to be very compelling. Taking notes, deriving tasks from them, etc., are not problems that I need solving. In fact, doing those things manually brings a very large benefit in terms of helping to clarify my thoughts, getting insights, and better remembering everything.

When I outsource that (whether to machine or another human), I lose a lot of benefit.
