In 1982, a sixteen-year-old boy in the Midwest sat down and wrote eight episodes of a television series about teenagers running a school newspaper. The characters drank in darkrooms. They brought guns to school. They had bone cancer and absent fathers and substance abuse problems that no adult in the building knew how to address. One of them wore orange overalls and ordered a razor from a magazine that promised to scrape away the dead sensuality, uncovering your natural, animal instincts. The blades cost seventy-nine dollars and eighty-eight cents. The razor cost three dollars and eighty-seven cents. That detail is the kind of thing only a teenager would write, because only a teenager understands the specific economics of being cheated by the adult world before you are old enough to know the word for it.

That boy was me. And for over four decades, those scripts sat in a drawer, and then in a file, and then in the particular purgatory of work that matters to its author but has not yet found its form.

Today I want to talk about what happens when you go back.

In the book I describe what I call the Substitution Test. Three questions. What human good was this technology supposed to serve? What did it actually deliver instead? And who profited from the substitution?

Those three questions govern every chapter. They are applied to the typewriter and the word processor. To the chalkboard and the learning management system. To the handwritten letter and the social media post. To the stethoscope and the electronic health record. And in every case, the answer reveals the same structural pattern: a genuine human need is identified, a technology is developed to address it, the technology achieves dominance, and during that dominance, something essential is lost. Not because the technology is evil, but because the technology is a tool being asked to be a god, and tools cannot be gods, no matter how sophisticated they become.

For twenty-eight episodes of this podcast, four cat heads floated through the universe looking for their bodies. Captain Whiskerfluff, gray-furred and philosophically inconvenient. Lieutenant Mittens, ginger, who told jokes the way the rest of us breathe. Cookie Kitty, calico, whose opinions about soup could be heard across three star systems. And Skeedootle, who was not a cat at all but a puppy, floppy-eared and enormous-eyed, adopted into a crew of felines because nobody could justify leaving a creature alone in the dark.

They lived here. On this podcast. In this voice. In the space between my microphone and your earbuds. Twenty-eight times, we visited them. Twenty-eight times, they argued and wondered and searched and did not find what they were looking for, because the search was the point, and because finishing the search in a podcast that was also about consciousness and memory and what it means to be a living thing in a confusing universe would have felt premature. The Cat Heads existed as audio drama. They were performed. They were voiced. They were heard and then they were gone, living only in the archive, waiting for someone to press play again.
