I chose Clash of Fates and Technological Singularity. My reasoning is as follows: several significant discoveries in the natural sciences have happened in particular advancements in neurology and the other life sciences. On top of that, two major social trends are indeed forming: ours and the neo-collectivists. This sets up a significant precedent not seen probably in thousands of years of recorded history (think real early Mesopotamia history...), so this won't be some easy clash either. I suspect at least one major change will happen: a new 'human' species will evolve due to whatever political, economic, and scientific wrangling that occurs. This species will decide the ultimate fate of itself and our current species. What I do see in the Pattern for this key event is that everything we know today will not exist as it does now. I do mean it, too. It will happen here in the United States only because the elements for social, scientific, and economic changes seem to be converging here for whatever reason. I suspect there are other forces at work, but nothing like what the conspiratards think. Personally, I think it's simply other folks like myself who can see the Pattern as well, but have their own designs for its shaping. They can't be happy with letting it unfold as it will, they wish to be gods, that's all I can guess so far.
