As usual Dave, you’re right on.
I would say the lack of a visual/graphical knowledge mapping/management mindset is clear within personal development, Academia and Business models at all levels.
I would use Wholistic rather than holistic, as I personally see knowledge systems we create as being static unless we inject context to the aggregated data of words, images and numbers we create and decide is information. Indeed this kind of contextualized information we call knowledge may become holistic in the sense that it may become usable and therefore become almost a living sentient (sic) thing (with the future inclusion of AI and AR).
But as usual Dave, you give us an article that can be expanded and exploded into all arenas where we use communication.
