In June, 1991, Al H. Morrison’s article, “Two Centuries of Pluto in Signs” appeared in The Mountain Astrologer magazine. He began with a backward look at Pluto in Gemini through Scorpio, then added a forecast of what he considered likely with Pluto in Sagittarius through Aries (ending in 2097). Here’s his take, over 30 years before the fact: 
Pluto will enter Aquarius on November 21, 2024. Traditionally, Aquarius is ruled by Saturn. In modern times we assign it to Uranus, the most reactionary of all planets. The action of Saturn is to hold everything as it is or was, in stable order. The situation/structure is a return to a vacuum, an empty space with perhaps some clutter of shattered bits and pieces of what has been.
The action of Pluto is revolution, mutation of individuals, and changes of consensus caused by such mutation. Aquarius has been thought to rule science, individual intellectual freedom, logic, fixed systems of rules, and independence (for individuals as well as groups or nations). It follows that Pluto arriving in Aquarian territory will upset our entire culture and change the way people think (or permit computers to manage everything). Aquarius is a very dry sign, not a very propitious environment for projects based on emotional or sentimental concerns.
We may have a planetary totalitarian regime during this tour of Pluto in Aquarius, perhaps required to cope with climatic changes, global nuclear and chemical pollution and other environmental problems. The most serious problem has not been addressed in the west in this latter part of the 20th century: what to do about overpopulation. First raised by Malthus early in the 19th century, it was countered by religious dedication to maximum birthrates. The mandate is yet to bring forth children “to fill the earth” in most religious groups. The basic question comes to such crisis as to force world action while Pluto tours Aquarius…
It is even probable that scientists will discover while Pluto is in Aquarius that time itself is not constant or uniform, but merely another confusing variable.
(Pluto enters Pisces on March 1, 2043.)
