We can talk about what high fidelity emulation includes. Will it be just your mind? Or will it be Mind + Body + Environment? In the most common case (with an absent body) most typically human feelings (hungry, thirsty, tired, etc.) will not be preserved creating a new type of an agent. People are mostly defined by their physiological needs (think of Maslow’s pyramid). An entity with no such needs (or with such needs satisfied by virtual/simulated abandoned resources) will not be human and will not want the same things as a human. Someone who is no longer subject to human weaknesses or relatively limited intelligence may lose all allegiances to humanity since they would no longer be a part of it. So I guess I define “humanity” as comprised on standard/unaltered humans. Anything superior is no longer a human to me, just like we are not first and foremost Neanderthals and only after homo sapiens.
Well, yes, a lot depends on what we assume the upload includes, and how important the missing stuff is.
If Dave!upload doesn't include X1, and X2 defines Dave!original's humanity, and X1 contains X2, then Dave!upload isn't human... more or less tautologically.
We can certainly argue about whether our experiences of hunger, thirst, fatigue, etc. qualify as X1, X2, or both... or, more generally, whether anything does. I'm not nearly as confident as you sound about either of those things.
But I'm not sure that matters.
Let's posit for the sake of comity that ...
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
