If you would like some thought on systems a step lower, Howard Blooms book global brain, argues that evolution has operated for billions of years as a "global brain" a worldwide, networked learning machine in which all organisms from bacteria to humans act as interconnected nodes, each a "hypothesis" tested by a collective mind that rewards successful groups and discards failing ones through group selection rather than only competition.

Unrelated, money behaves very similar mimicking or hijacking naturally occurring systems this "global brain", unlocking society.

But your question is less about who are the greatest thinkers of our time and more of about who can traditionally formalize and distribute their thoughts the most.
