When you make the term "general intelligence" so broad that it expands beyond the realm of human senses & concepts, statements about it become unfalsifiable because you, a human, can't conceive of a way to test said statement.

Unfalsifiable statements are worthless because they can't be tested.

So, at the very least, there's no point in humans trying to theorize about intelligence so general that it expands beyond human comprehension.

Basically, in the context of universal intelligence, I'm an atheist & you're agnostic.
