If the modifications go far enough (e.g. something like completely suppressing all human emotions) I'm pretty sure it's fair to say that we'll be gone. At least

If the modifications go far enough (e.g. something like completely suppressing all human emotions) I'm pretty sure it's fair to say that we'll be gone. At least I don't see any reason why we should view these potential future 'humans' as any thing more related to us than say a potential 'species' of robots.
