For tired and late, you sure write well.
You  covered most of my thoughts, beyond the pleasure of the book itself (which has so far gotten short shrift here).
Small addition:

In essence what technocratic culture does is to Enclose competence and knowledge in the hands of an elite caste of designers, planners, and engineers, while removing and "obsoleting" more and more skill and knowledge from the work and lives of the masses of their fellow citizens.

It goes beyond that. That "elite caste" of technocrats think they are the crown of creation, but they are thenmselves a tool- and the top of the food chain here is the corporate oligarchy- that one quarter of a percent who likely cannot (and need not) ever change a tire. They have a vested interest in keeping the "lower orders" mesmerized by technology and it's toys  -ignorant- and therefore dependent and easily manipulated.
Us technocrats will then change the tires of the world for them-- and the  recipients of the largest capital redistribution in history dispense the illusion of power to the technocrats to just exactly the degree needed, and no more.

Of course, it aint that simple-
But that's the next layer, Deanander.  


Capitalism searches out the darkest corners of human potential, and mainlines them.
