It is impossible for us to know what this would be like.  I agree with you that it is probably preferable to ceasing to exist, and could possibly turn out to be much better.  I think we have no way of knowing what the virtual equivalents are for misery and happiness if one were in electronic form.  Perhaps misery might be things like a computer virus, a slow processor, unreliable electricity.  It's very hard to know what would constitute happiness.  I think it is possible that some of the things that cause flesh-and-blood humans to feel misery and happiness would still do so if we were in virtual form.  These might include caring about what happened to others, interacting with others, etc.  In our current form, the body plays a big role in both misery and happiness.  Things like eating, skiing, making love, etc. might not bring much pleasure to a computer.

If you want to increase happiness, though, decreasing misery works pretty well.  My understanding is that people have a happiness set point, which is mostly fixed, and determines how happy they are \"by default\".  Misery pulls happiness down from there.  Short term, lots of other things can move you up or down, but long term, in the absence of misery, people tend to be pretty close to their set point.  Some activities (meditation, physical activity, social involvement) can bring people up, but it's very difficult to improve over someone's natural happiness level once you've removed sources of misery.  I haven't studied this very much, though, so if this is contrary to your understanding (and experience as a therapist) I would be interested to hear.<br><br>Or is your objection to the idea of a single happiness continuum, accounting for both happiness and misery, on which each person has a current (and average) position?<br><br>\"I think we have no way of knowing what the virtual equivalents are for misery and happiness if one were in electronic form.\"<br><br>In the case of \"uploaded\" people, where your brain is scanned (destructively, probably, so when you're near or at death) and then loaded into a computer simulation as a program, happiness is probably quite similar to where it is now.
