AIM 3-2-1 says that it is the responsibility of the pilot to insure that ATC

controllers that it is their responsibility to coordinate the passage
through that airspace of flights to which they are providing services. Which
is right??

I don't see any conflict. The AIM tells me that it's my responsibility to handle
things before I enter the controller's airspace and the ATCH says it's the
controllers' responsibility after I get in there. Two different scenarios and
locations in the air.
