I thought of this too, but with scheduling as well. So I could add "buy gloves", and it will try to fit it into the schedule and optimise it for when I'd be close to a shopping centre (e.g. for flat visits or groceries, etc.).

Same for wanting to do 5 hours of exercise a week, around work hours. What to focus on within working hours, etc.

With Alexa and Google Calendar, we're pretty close already.
