These Dharma employees are told that Dharma hasn't existed for 20 years, and that they've been receiving directions from an automated system for that entire time. They're offered an answer to one question each.
Neither of them think to ask, "who's been feeding, supplying, and paying us for the past 20 years?"
Again and again, LOST is a lie. Even the answers to questions aren't real answers.
PS. The two last sentences of Lost are Walt asking Hurley, "Why?" and Hurley changing the subject. How absolutely appropriate. The novice of denying information to the audience has become its new captain.
