That's the same as "I".

Well, yes. What I was trying to do was avert a confusion where "I" might refer to an instance (meat brain, silicon RAM copy #224) or might refer to a class (the abstract computation they're both running), by specifying the intended meaning. That is the point of tabooing, right?

I'd say that past!you, upload!you, and meat!you are three distinct instances of the class you.

Thanks; this seems to be the source of disagreement. I see two instances, not three, the second forking at the moment of upload and running the same program with a new PID. I don't think we'll find common ground here, and I'm not sure I'm up to defending my position on the subject. I just found the consequences of that position interesting to explore.
