Imagine that virtual reality equipment becomes so sophisticated that it can simulate sound, smell, taste, and touch as well as sight when you are wearing it. Imagine, too, that the programming becomes so elaborate that you can have decades-long virtual reality experiences, not just brief encounters. Imagine that it is also possible to program it to simulate experiences that are entirely pleasurable or happy, and entirely devoid of pain and anguish. Under those circumstances, would you be willing to give up real-world interactions and engage only with virtual reality fantasies? Why or why not?
