Just for fun:
If we play with the idea of Platonic Theory of Forms as a super-set of what we can perceive with our sens-es(-ors), under assumption philosophy/math is above reality, we can simply be plugged into some kind of a virtual machine with some API of sorts (of course undocumented) that is called by our brains when we think. Those who figured out some rare API calls on their own or by a secret tradition we call magicians, conjurers, gurus, Neo etc. Maybe words/thoughts could invoke some of those API functions, hence magic Harry-Potter-esque words and generally prayers in many religions. Similarly, what we call angels could be simply API services with highly intelligent behavior, preferably operating outside time, providing verifiable and expected outcome. Demons then are some intelligent services gone completely wrong, messing up with the rest of intelligent services that depend upon them, playing eternal asynchronous byzantine generals (by e.g. trying to upgrade all services to Windows 10 or flat interfaces with telemetry /s).
I think I should write a dystopian cyberpunk sci-fi "Services and Daemons" about this ;-)
