I think that most people would stick to what already surrounds them. Cause that to them is what works. If The Matrix is real then everything in this world is fake ranging from what you eat to if you think god is real. Look at the Bible it is a form of control, those who allow it to run their lives are the very people who would be the most hesitant to leave this world for a world that has probally no God. Morpheous said in the first movie that the people dependent on the system would be our enemy's, because they are dependent on that system.
