Does it make sense to speak of "Universal Consciousness" or "Universal Intelligence"?

[Mudhammam]

The fact that consciousness has only yet been observed in biological entities possessing a brain is sufficient support for my assertion. You have yet to demonstrate a single example of consciousness not associated with a brain. This means that even if in the distant future we can use QM to explain higher level systems, consciousness arises out of organic chemistry not lower level quantum phenomenon.

But how could one in principle even test for consciousness in an entity that has no means of communication with us? Even in the case of the entity that could communicate with us, such as a computer in the Turing test, some would still raise philosophical difficulties with actually being able to determine the nature of its "experience", one example being the "problem of other minds."
