Did Dr. Richard Day really predict it all in 1969?

Something interesting I came across was a book entitled "The New Order of Barbarians". The book is based on a series of taped interviews in 1989 with Dr. Lawrence Dunegan, a pediatric doctor, who attended a lecture in 1969 given by another pediatric doctor - Richard Day. In this lecture, rather than talk about medical matters, Day allegedly asked everyone present to turn off any running tape recorders and cease taking notes. He then began to talk about something else entirely, Dr. Dunegan claims, and identified himself as a member of "The Order", a group of connected and presumably highly influential individuals who were creating a plan for humanity, and had essentially mapped out several big social and technological changes that would occur over the remainder of the century. Dr. Day then began to lay out this plan for humanity to those in attendance in great detail and in an almost confessional tone, and although Day had supposedly asked those present not to take notes, Dr. Dunegan did so, anyway. He would then recall 20 years later what Day had said that day, allegedly.

The audio is available for free, here. The bullet points of Day's alleged claims are available here.

My questions about this are whether this alleged event is known much in conspiracy circles, what the credibility of Lawrence Dunegan is, and what you think of the prescience of the predictions were as they were recalled by Dunegan in 1989?
