Back in the 1980s, I lived in Redlands, California, when the last adherents of this movement were still alive. From my conversations with them, it seemed the movement evolved into a semi-new age cult ala Scientology and the Process Church of the Final Judgement[1] (the original cult, not the one borne later, from the time later Skinny Puppy album). In the end, it felt like an anti-technology movement.

There was significant overlap between Scientology's Dianetics and Technocracy. At that time, they didn't seem to be very technology-inclined or tech-positive.

Nonetheless, despite being in their 80s or 90s, they were still quite devout and had their clothing and automobiles decorated with Technocracy ephemera.
