Patrick Wood is the pre-eminent expert on Technocracy, what it is, where it originated, by whom it is promoted, how it is merged into populist movements; and, perhaps, how it's onward march may be contained or stymied.
Of course, to really put it back into its box we would need to foster an alternative vision, but currently we don't yet have any clearly defined alternative, since the old models of democracy based on political parties, or even on religions, have been shown to be both corruptible and corrupted.
In this technological world, perhaps we need a vision that would harness technocracy in the interests of the people rather than in the interests or fantasies of the self-appointed elite. A tall order? Perhaps, perhaps not, but we need to get to work on it.
So leaving the alternative vision aside for the moment, what we do have is a series of 12 articles by Patrick Wood, that review the history and modus operandi of the would-be technocrats, and which you can peruse here.
(If you're new to the concepts of technocracy, start here.)
At least we can better understand whither our unelected elites are taking us.
