Sure, modern science mostly exists by taking broad swathes of common human experience, declaring that it doesn't exist, and then browbeating everyone else into agreeing with them. It wasn't that long ago that "Plate Tectonics" or "Meteorites" were labeled as pseudoscience that serious people didn't believe in.
Something that frequently frustrates me is how effectively science is able to ascribe previously commonly held scientific theories that have been proven wrong to "superstition," "magic," or "religion." No, that was Science(tm), and it was wrong, and it frequently hurt a lot of people when the error was compounded by the arrogance of Science's prophets.
It's probably obvious by the kind of comic I'm making where I sit.
That said, even a spirit releasing sword isn't particularly useful from a serious military perspective. Sure, you can instant death me in melee. But I can instant death lots of people from 20km+ away with artillery and reliable intelligence. Give the Russians a thousand such swords and they won't be any more effective against the Ukrainians.
I will admit that a doctrinally correct "Fire Mission" with modern artillery would be pretty boring in media though.
...Man I gotta do the second page of that Akala comic. The contest has me distracted, forgive me.
