I have a conspiracy theory that goes something like this. So when God created Angels, a third of them chose to rebel. But what are Angels?
Angels are entirely spiritual beings without physical bodies, similar to God in their non-physical nature. Unlike God's pure simplicity, Angels have an angelic substance as well as distinct intellects and wills. When Angels communicate, they do so through telepathy, and once the other Angel consents, they can "speak" mind to mind. Higher-ranking Angels can not only share concepts with other Angels but also enhance the other Angels' understanding of those concepts beyond their natural capacity. An Angel's position in the hierarchy is directly related to their intelligence.
In Heaven, the hierarchy of Angels is purely based on their nature. From the moment of their creation, Angels were infused with the essence of all created things. They instantly knew what a tree, a dog, a human, and all other beings are. However, Angels do not have foreknowledge of particular events in time; this knowledge is given by God as events occur. They lack God's omniscience. This means an Angel can think about a concept, like humanity, and focus on individual humans and their actions at any given moment. Humans, on the other hand, observe many individuals to understand what it means to be human, using inductive reasoning. So, when an Angel contemplates a concept, they fully and instantaneously grasp everything about it to the extent they are capable (with higher-ranking Angels able to understand more). If an Angel wants to know what's happening on Mars, they simply focus their intellect on the concept of Mars and immediately see what's occurring there.
Different Angels will specialize in different functions, and since each Angel is in actuality an entirely different species from another Angel (To be an "Angel" is an office, and is different from the nature of a spirit itself). For example, Principalities are known from scripture to be angelic beings with authority over groups of nations and institutions, they can even have authority over corporations. They would likely have enhanced insight into governance and leadership, what makes a just leader, how people should be organized, and a greater understanding of societal structures, cultural developments, and general behavioral patterns of large communities. They would understand how all the complexities of social, political, diplomatic, economic, scientific and spiritual dynamics interconnect in a way that no human being could. What you should be getting from this -- is that while modern corporations are publicly releasing super-computers and AI that are capable of providing condensed information on nearly any topic at a whim, these pale in comparison to what an Angel can know and do. It may even be the case that many of the recent developments with releasing AI to the public were influenced by principalities. Since it is an open-secret that computers with super-capabilities have been at large for a long time, even as early as more than a decade ago, when rumors about CAIMEO and other corporate or government-owned quantum computers were circulating, and it was said that one could purchase its services. It is not uncommon, likewise, for spirits to be consulted when it comes to modern events. Everyone knows that Adolf Hitler employed Karl Ernst Krafft who made predictions that were taken seriously by the Nazi regime. Ronald Reagan consulted the astrologer Joan Quigley, and Charles de Gaulle consulted with Jeanne-Francoise Villepreux. The same was also true of Mikhail Gorbachev. Modern psychics of similar influence include Marina Abramovic, who was a known disciple of Joao de Deus (John of God). She was recently requested by President Zelensky to be the Ambassador for the Ukraine. Likewise, much has been made of the CIA"s attempts to weaponize remote viewing throughout the 1980s, 1990s, and the British Ministry of Defense has conducted studies on psychic capabilities as recently as 2007. The influence of all this on our world leaders can be best understood by watching the ceremony of the opening of a tunnel in Switzerland, which was attended by a great deal of the worlds leaders, and by looking at the Wikileaks documents which show that many prominent figures in the United States government today and previously have likely engaged in pedophilic sex magic not unlike the practices that were written about by the occultist Eliphas Levi, who wrote that a male child is a "most pure victim". Now, what do the businessmen of Corporations seek? New ways to predict the future of course, in the context of furthering their ambitions, and profits. What do politicians of Nations seek? Various things, but for evil politicians this is almost always done by attempting to predict what their opponents will do next, they employ hatchetmen, spies, and every sort of tactic that can increase their odds against their adversaries. That is partially why the advancements in AI are so rapid, since they are a most material way to obtain knowledge. But if it is the case that they can only mimic a fraction of a Demons power, which would you prefer to consult?
In either case, these people of influence are easy targets of demons since they have many personal ambitions, borne of avarice, envy, pride, or even malice. We see a high correlation of political manipulation with those who consult with demons. For example, the Cabonari, which is an offshoot group of freemasonry spent their time working to overthrow various nations such as Portugal, where Carlos I, the monarch of Portugal was assassinated by freemasons associated with the Cabonari. Similar movements gave birth to many revolutions in South America, including ones associated with the rise of Che Guevara who was famously said he would not hesitate to "squish him like a worm" when speaking of Christ.
Perceptions of the paranormal, such as UFOs (which appear to originate from the sea), or common accounts of abductions associated with molestations. Likewise, perceptions of "Mandela Effect" and "altering timelines". The rise of "meme warfare" associated with the worshiping of the "frog god" can be connected to these things in ways that may still yet be unforeseen.
So what does this all mean?
Since Demons are not granted omniscience, yet are gifted with super-intelligence. Their focus will be on predicting the future, since we already know their goal is to maximize damnation. For example, an Exorcist once received a prediction from a demon in the very early 2000s that things would start to really heat up around 2009. By studying the patterns of human behavior, combined with everything else they can calculate, they may be able to see a general trend. The issue with demonic calculation, is that since they are not able to see in what way God will bestow grace upon individuals, they are often taken by surprise regarding this, and this will throw off how they think things will go. This is why Demons cannot actually give prophecy, they can only give predictions which may seem very likely.
Nevertheless, their predictions will, without any doubt, surpass any super-computer that we possess in the modern day, whether hidden from our view or otherwise. Therefore, all of their machinations are done with design, even those that are seemingly random influence the world in a way that they wish to use to drive things towards greater moral corruption.
