this argument hinges on how fault tolerant you regard identity to be. You can not isolate the computers from all error. Let's say part of the error correction involves comparing the states of the two computers, would any correction be "death" for one of the simulated you's?
bottom line: not interesting, revisit question when we have more data.
Suppose I have choice between the following:
A) One simulation of me is run for me 100 years, before being deleted.
B) Two identical simulations of me are run for 100 years, before being deleted.
Is the second choice preferable to the first? Should I be willing to pay more to have multiple copies of me simulated, even if those copies will have the exact same experiences?
Forgive me if this question has been answered before. I have Googled to no avail.
