In reality, the world has been changing for many years, but many prominent actors benefitted from the changes remaining hidden. Simply because their wealth and power and worldviews are better served that way.
It's entirely unclear whether we will ever get a chance to see to what extent the efforts to hide developments have been successful, or even been perpetrated at all, because we don't know to what extent truth and reality will be accessible in the future.
What we can say at this point in time is that the changes 2016 delivered were urgently needed. There are many people out there who just want to turn back the clock, and change everything back to how it was, but they can't, and that's a good thing, because the way things were was hurting too many people.
2016 will go down in history as the year when a big divide between groups of people in the western world became visible, a divide that had until then been papered over by real or imaginary wealth, as well as by ignorance and denial.
