But control of the body in general seems to pose no problem as they can cause the possessed to exert supernatural strength.
In researching this issue just now I found very little information regarding supernatural strength although we know it occurs.
With respect to robots and AI the proper term seems to be infestation rather than possession. Evil spirits can infest all manner of things from forests, machines, Ouija boards, talisman, buildings, and so on, so will have no trouble with Artificial Intelligence and robots.
Regarding the occult, it is of Satan's kingdom and covers everything from nature religions, the Mysteries, Luciferianism, materialism, pantheism, ideology, evolution, Darwinism, witchcraft, sorcery, magic, occult devices, and so on. For more on the occult buy a copy of Dr Kurt Koch's "Occult ABCs"
Thx much. Good info.
