>Is thought leader the next evolutionary level of the "idea guy"?
With 40 years and counting in this particular sub-field of anthropology, it's been fully confirmed that the so-called "Thought-Leader" (Ignoramus Rex) does not fall within the evolutionary branch of the now-extinct "Idea" man (Traumus Pieintheskii) whatsoever.
On the contrary, Ignoramus has now been shown to be an evolutionary dead-end that arose from lower-intelligence forms than those which gave rise to Traumus. As we have seen from intact specimens, Ignoramus is simply not capable of achieving the level of sophistication in its natural environment as Idea Man once exhibited during the brief epoch when it was thriving.
Yes, I would say so, nice observation.
I also think that many "idea guys" are doing the performative role of "the leader", i.e. the idea guys doing the corporate/business drag of the "thought leader".
