Perhaps only a fraction of humanity would upgrade. It might be they who are the instigators of the purge of the remainder.
There's no "perhaps" about it. We're a species right now with a massive
disparity between wealthy and poor; a few thousand well-placed political and industrial elites already make decisions that affect (and often devastate) the lives of the other 6 billion people here. One way or another, a small group of individuals would use the "upgrade" to either protect their privileged position, or to gain that position in the first place. Either way, everyone else is screwed.
