If technology advances to the point of recreating the world almost perfectly in a virtual reality (i.e. The Matrix), would it be morally acceptable to "move" into that world indefinitely? Let us assume there is a moral disparity between someone with/without family, friends, attachments moving into this virtual reality. Let us also assume there is no cost to sustain anyone's well-being in this distant future, either in this virtual world or the real world, such as rent or food. Perhaps in this virtual world there are new fun things to do, like flying freely, that in the real world one could not do. There is seemingly no catch to this, but is there a moral obligation to remain in the "real world" and do "real things?"
