We dream of #2. Maybe we can get to #1 if we work really really hard.
#6: Given that we live in a hostile universe with no meaning other than what we ascribe to it, who's to say that entering into a permanent state of bliss is somehow wrong or immoral?
Who's to say? Sounds kind of boring though -- except for people who are in a permanent state of suffering.
I don't under any circumstances buy the "inherently hostile universe" argument. The universe is the most neutral piece on the game board. If anything, humanity is the inherently hostile blitzkrieg. (I don't believe that the universe has no meaning, either. I just hate that sentence you quoted, I guess!)
I think #5 seems likely. More and more we are heading in this direction anyways as people are less "in the moment" and are more dialed in to technology or even their own internal dialog.
