I agree that the people are ready, even desirous, of change. I suspect even the Davos class is ready. I just worry about the bureaucracies.
If you look at the glacial process by which the “Public Health Industrial Complex” is de-emphasizing carbs, then it’s clear that it not just the magnitude of the revelations but the cost to the bureaucracies that run our world that affect the pace of disclosure (a lot of dietary advice recommendations have to be changed, school lunch programs, physician reeducation and a very painful reworking government grants.) An official acknowledgement of an intelligence apart from the “consensus civilization order” (it perfectly possible that many of these “aliens” are Earth based, so I’m not keen on alien or extraterrestrial as a category would be a far greater challenge for the bureaucracy. So I can see it taking six years or even twenty years of theologians, bureaucrats, and accountants hammering things out.
I think the biggest issues is coming to an understanding of that past that governments, TBTB, and the larger culture can agree upon and not just in terms of what did the governments know and when did they know it. That’s relatively easy-- Great Power competition is messy and things happened will suffice for most people. The US has a decent cultural machine for reordering the past and reassigning heroes and villains. Whitley Strieber High School may one day be a thing.
My guess is that the larger cultural issues are what’s holding up the process. A fair amount of historical understanding and religious doctrine can be reconciled with an open acknowledgement of The Others, The Visitors, or whatever the term is settled upon, but that is work that must be done. Some is writing a The Chrysanthemum and the Sword type treatment that is so much harder in reverse–who are the advanced beings, who may or may not be pulling the strings and who have (presumably) been here a long time. How do we deal with them? What stories do we continue to tell ourselves about our past, particularly our religions and the historical events that gave rise to our current world. That is what is taking so time. Well, that and going over Lockheed’s new proposals for the Federal Armed Services.
