>> It is more a test of humaness
Very true, but if we consider humans to be intelligent (which is debatable), then it makes sense (to me at least) that something that passes for a human could also be intelligent. Granted, this is only a small subset of things considered intelligent, but it is the most easily definable one.
The 'quantum mechanical magic' doesn't really make sense as an argument (which I know is what you're saying). Things on the quantum level do not (apparently) follow causal laws, but rather random probability. On large scales, however, the 'laws' are approximately causal (close enough for government work, so to speak), but those quantum laws apply to everything, not just humans.
