For anyone else spotting this ...incredibly long rant, I'll counter by simply pointing out that multicellular organisms are altruistic collectives of individual cells which survive best when all constituent parts cooperate. There is no central authority in any biological system. All parts simply communicate and process in extremely complex ways which defy hierarchal categorization.

Cancer on the other hand is a breaking of that altruism and excessive hoarding of resources to the point where it self destructs the hosting system that was letting it survive at all.

This individual's unique understanding of "four brains" isn't accurate nor detailed with how biological systems work, humans or otherwise, and fails to address the simple counter example of "what about plants though" or any other myriad of other counter examples.

Even non multicellular organisms often benefit from and perform rather incredible acts of altruism, and do so all on their own accord, nobody "above" organizing the process.

Cheers folks.
