# Intro
## July 13, 1958 - Electronic Brain Teaches Itself
The Navy last week demonstrated the embryo of an electronic computer named the Perceptron which, when completed in about a year, is expected to be the first non-living mechanism able to “perceive, recognize and identify its surroundings without human training or control.” Navy officers demonstrating a preliminary form of the device in Washington said they hesitated to call it a machine because it is so much like a “human being without life.” Dr. Frank Rosenblatt, research psychologist at the Cornell Aeronautical Laboratory, Inc., Buffalo, N. Y., designer of the Perceptron. conducted the demonstration. The machine, he said, would be the first electronic device to think as the human brain. Like humans, Perceptron will make mistakes at first, “but it will grow wiser as it gains experience,” he said. The first Perceptron, to cost about $100,000, will have about 1,000 electronic “association cells receiving electrical impulses from an eyelike scanning device with 400 photocells. The human brain has ten billion responsive cells, including 100,000,000 connections with the eye.
# Intermission A
## Difference Recognized
The concept of the Perceptron was demonstrated on the Weather Bureaus $2,000,000 IBM 704 computer. In one experiment, the 704 computer was shown 100 squares situated at random either on the left or the right side of a field. In 100 trials, it was able to “say” correctly ninety-seven times whether a square was situated on the right or left. Dr. Rosenblatt said that after having seen only thirty to forty squares the device had learned to recognize the difference between right and left, almost the way a child learns. When fully developed, the Perceptron will be designed to remember images and information it has perceived itself, whereas ordinary computers remember only what is fed into them on punch cards or magnetic tape. Later Perceptrons, Dr. Rosenblatt said, will be able to recognize people and call out their names. Printed pages, longhand letters and even speech commands are within its reach. Only one more step of development, a difficult step, he said, is needed for the device to hear speech in one language and instantly translate it to speech or writing in another language.
# Intermission B
## Self-Reproduction
In principle, Dr. Rosenblatt said, it would be possible to build Perceptrons that could reproduce themselves on an assembly line and which would be “conscious” of their existence. Perceptron, it was pointed out, needs no priming.” It is not necessary to introduce it to surroundings and circumstances, record the data involved and then store them for future comparison as is the case with present “mechanical brains.” It literally teaches itself to recognize objects the first time it encounters them. It uses a cameraeye lens to scan objects or survey situations, and an electrical impulse system, patterned point-by-point after the human brain does the interpreting. The Navy said it would use the principle to build the first Perceptron “thinking machines that will be able to read or write.")

Alexandra Alex Fletcher is a guest on Countdown. She is an actress, best known for her roles in Brookside as Jacqui Dixon from 1990 to 2003 and in Hollyoaks as Diane Hutchinson between 2010 and 2026. Her daughter, Yasmin is also an actress with both of them appearing on Hollyoaks together in 2025. [https://wiki.apterous.org/Alex_Fletcher]
Countdown on Channel 4 was directly adapted from the French Des chiffres et des lettres. Had English never abandoned the primary Middle English sense of the word, Countdown could have easily been called Ciphers and Letters. This etymological alternative reveals a fascinating case of historical polysemy: it would have denoted Digits and Letters within an educated register, while simultaneously yielding the sense of Codes and Letters to the remainder of the populace.
This semantic variation exposes a glaring category error in the Australian adaptation of the format, clumsily titled Letters and Numbers. By pairing the structural unit of orthography (letters) with an abstract mathematical construct (numbers), the title violates structural parallelism. The French original avoids this asymmetry by adhering to a precise taxonomic hierarchy taught universally to school children: “Les chiffres forment les nombres, comme les lettres forment les mots”(Digits form numbers, just as letters form words). By crossing these distinct tiers of classification, the Australian title breaks this linguistic and mathematical symmetry, forcing an asymmetrical relationship between a discrete meronym (the building block) and its holonym (the final conceptual product).
Modern tech parlance suffers from an identical taxonomic collapse when people use the phrase “an AI” to refer to a single algorithm or large language model. John McCarthy coined Artificial Intelligence as a mass noun to classify an entire academic field of study, not a countable noun for a specific tool. Collapsing the boundary between a discipline and its output forces a profound grammatical absurdity; using an AI to describe a piece of software is as illogical as calling an individual apple “a Biology.”
