</div></blockquote></div><div>That seems a reasonable assumption because from your point of view the computer simulating you can be infinitely fast. If there is a data processing crunch then the computer can just stop your simulation for a second or a minute or a millennium while it calculates exactly how that teacup you just dropped should shatter, when it figures it out then then it can start your simulation up again; from your viewpoint the computer was infinitely fast with its calculation it even if objectively it was as slow as an old Radio Shack TRS-80.</div>

</div></blockquote></div><blockquote type="cite">There would be only one conscious experience provided the two were identical.</blockquote></div></div></blockquote><div>How's that? You've got two independent instantiations running on completely different substrates and you don't think there are two different consciousnesses?</div>
</div></blockquote></div>No I don't think there are two different consciousnesses. The concept of position is not very meaningful when talking about consciousness, and what particular substrate a consciousness is running on is so unimportant that it often has no idea what it is. For thousands of years many thought the liver was the organ that generated consciousness, others thought the heart, and the ancient Egyptians carefully preserved every part of the body EXCEPT for the brain which they just threw away. </div>
</div></blockquote><div><br></div><div>It's not just a difference of position. As you've pointed out above, the clocks of the different substrates can run at different rates. And, obviously, the "universes" available to each can be different--there's nothing that says they all have to implement the same physics. </div>
