Ray wrote a later story ("I Don't Care Who Keeps the Cows") in which there becomes a trend of different kinds of brain-enhancement technologies to make everyone super-intelligent. Of course, the enhancements are sold by hucksters who are using the enhancements to control the enhanced.

When I first encountered this story, it felt like utter madness, something Philip K. Dick would write.

It's been wild to reflect upon this story during this past decade.
