Q: My complexion is hardly relevant.
BOND: Well, your competence is.
Q: Age is no guarantee of efficiency.
BOND: And youth is no guarantee of innovation.
Q and Bond get into a brief but heated debate about age vs. experience. Q thinks Bond is old and tired, while Bond thinks Q is young and incompetent. Both men may be right in their own narrow-minded ways: Bond couldn't hack into a computer system any more than Q could accurately fire a gun. The mutual ageism isn't winning either man any points with the other.
