When the singularity occurs and you get uploaded, what happens to your meatspace body? Is the upload a “move” or a “copy”? If it’s a copy how could you stand waiting around to die in a few decades, knowing that there’s an immortal you somewhere out there?

I could be wrong here, but I think the idea is that you will augment what you have to the point that the meatspace body will shed its layers one by one. Eventually there wont be one. Precisely what you link to. And no, it’s not the same.
However, what’s the difference between replacing cells with silicone as opposed to new cells?
