Like tasks applied at different levels of horizons. Contexts can be applied to multiple states of being.
Contexts will find you in different geographical locations, mental/energy states, social situations, current momentum (being in the zone), and in different focuses of horizon.
You could say that at any given moment your current is actually a combination of several sub-contexts. At that moment any combination of such contexts might trigger a particular best next action.
So I don't think its time to forget about contexts. Its time to realize that you are probably better able to describe the particular context you are in, and should recalibrate your organization appropriately.
