Was the ant with the mushie growing out of its head alive .. or dead ?? (It looked dead to me !)
I agree the research he has done has immediate benefits to humans .. no doubt about that .. I was a little wary at the point where he intimated that he'd saved his mother from metastatic cancer though .. he carefully did not say whether the mushrooms were what saved her (or chemotherapy .. or some other medical treatment .. or … ??? ...)!
The networking thing (complete with feedback) is a characteristic of complex systems, with components obeying simple rules. It works both ways too, ie: the local environment causes changes in the organism, (ie: genetically), and also the organism alters the local environment. The area of overlap with the internet analogy behaviour comes in the form of Complex Systems Theory even though the causality drivers are clearly different. Great stuff, this complexity theory … I love it .. (and I know you know everything I just mentioned.

)
I must admit I was thinking about the symbiotic relationships between insects and fungi during the video … the end thought was that this guy is only looking at a small part of the complete end-to-end process. I have concerns about cherry picking parts of such a process .. just to satisfy an immediate need (a a political/business need). Mind you, cancer sucks and I'm all for the cherry-picking when it comes to cancer cures! We haven't the slightest clue of what impacts mankind's excursions from the controls of evolution will have on anything else, though. I find this disconcerting.
I thought you didn't like cats ?? The loop is most certainly not closed .. unless you revert to your rifle-toting past behaviours, that is.
