I don't care about total utility, so arbitrarily many copies of myself with a worse life is strictly worse than one with a better life to me. The subjective experience of each one will be that they exchanged a better life for a worse one, and each one will be identical. I do not accept the offer. I think the morality of accepting this offer depends from person to person.
On the other hand, I think a lot of people would take this offer if they themselves were paid handsomely and did not have to become a serf, but their copies did.
I don't care about total utility
It's not clear what this means, and for reasonable guesses about that there seems to be no way for you to know the truth or falsity of this statement with significant certainty.
(Unless you mean that your emotional response or cached opinion is this way, which answers the original question to some extent, but in that case the specific phrase "I don't care about total utility" seems to be pretending to be an additional argument that justifies the emotion/opinion, which it doesn't seem to be doing.)
The first draft of the 2012 Less Wrong Census/Survey is complete (see 2011 here). I will link it below if you promise not to try to take the survey because it's not done yet and this is just an example!
2012 Less Wrong Census/Survey Draft
I want three things from you.
First, please critique this draft. Tell me if any questions are unclear, misleading, offensive, confusing, or stupid. Tell me if the survey is so unbearably long that you would never possibly take it. Tell me if anything needs to be rephrased.
Second, I am willing to include any question you want in the Super Extra Bonus Questions section, as long as it is not offensive, super-long-and-involved, or really dumb. Please post any questions you want there. Please be specific - not "Ask something about abortion" but give the exact question you want me to ask as well as all answer choices.
Try not to add more than five or so questions per person, unless you're sure yours are really interesting. Please also don't add any questions that aren't very easily sort-able by a computer program like SPSS unless you can commit to sorting the answers yourself.
Third, please suggest a decent, quick, and at least somewhat accurate Internet IQ test I can stick in a new section, Unreasonably Long Bonus Questions.
I will probably post the survey to Main and officially open it for responses sometime early next week.
