If someone gave you the opportunity to live in the machine for the rest of your life, would you? You can't go in for just 5 minutes - you can either go in for the rest of your life, or never.
Most people hesitate because there's a catch: we're never really going to see our loved ones again; we're never really going to make a difference. We are no longer of any use in the real world. In the words of Robert Nozick, going into the machine makes us an "indeterminate blob".
So what does this say about us humans? It says that we value things beyond pleasure and happiness. We value reality. One might see this as having implications for the theory of Psychological Egoism, which suggests that we do things only to make ourselves happy.
