How fast it comes on How this was no warning How there was lots of warning How we shoulda known How nobody coulda known How it completely takes over society immediately About the long drawn out wars fought for it to take over society How society splits between those under it's affects, and those not How prevalent the effects are How exclusive the effects are How big, how small etc, etc, etc
There are billions of humans out there right now, imagining all manner of things, and it's irritating to me to see all the hand wringing over the "Nobody stopped to think if they should". Lots of people did, and are, asking that question.
