Since this is a crazy ideas thread, I'll tag on the following thought. If you believe that in the future, if we are able to make ems, and we should include them in our moral calculus, should we also be careful not to imagine people in bad situations? Since by doing so, we may be making a very low-level simulation in our own mind of that person, that may or may not have some consciousness. If you don't believe that is the case now, how does that scale, if we start augmenting our minds with ever-more-powerful computer interfaces. Is there ever a point where it becomes immoral just to think of something?
