And some human supremacy thinking isn't completely pointless? Humans are far from the best in everything but logical and certain emotional brain power in this world. And since Gon can use nen splendidly, we know with 100% certainty it doesn't depend on one's intelligence.

The difference between magic and nen (chi) that I was referring to is that magic often requires different sorts of rituals, mumbling arcane spells, drawing magic circles, using ingredients, staves, whatever. Chi, however, doesn't require anything of that sort (at least not for everybody in HxH. Some have certainly had spell like details). Some nen users we have seen are sort of living in perfect harmony with their special kind of nen (like some of the shadow beasts, for example).
