An extract from George O. Smith’s short story QRM INTERPLANETARY (1942), the first of his works about a space station set up to relay radio messages between Earth, Mars and Venus:

On Monday, Francis Burbank sent around a communique removing the option of free messages for the personnel. On Tuesday, he remanded the years-long custom of permitting the supply ships to carry, free, packages from friends at home. On Wednesday, Burbank decided that there should be a curfew on the one and only beer emporium. “Curfew” was a revision made after he found that complete curtailing of all alcoholic beverages might easily lead to a more moral problem; there being little enough to do with one’s spare time. On Thursday, he set up a stiff-necked staff of censors for the moving picture house. On Friday, he put a tax on cigarettes and candy. On Saturday, he installed time clocks in all the laboratories and professional offices, where previous to his coming, men had come for work a half-hour late and worked an hour overtime at night.

and about a month later it escalates to this conversation:

New paper: LLMs don’t do formal reasoning.

Well, of course.

LLMs don’t do informal reasoning, either.

Humans are great at pattern recognition. We even recognize faces in clouds and tree trunks. We recognize wheelbarrows, bears and crabs and archers in the stars. We make things that have meaning, and we communicate through speech and text and art.

LLMs are great pattern-generators. They are extremely well-tuned to make patterns that look like they might have meaning. A human trying to communicate may be bad at it, but they have an underlying model of the world that they are referencing and updating. An LLM is not trying to communicate anything. An LLM has a model of language, not a model of the world.

The map is not the territory. All models are wrong, but some are useful.

The situations in which it is reasonable to use an LLM are exactly the situations in which it is reasonable to roll some dice and use that to read the table of random monster encounters; to pull a card from an Oblique Strategies deck; to twirl the knobs on the synth and see if you can get a cool sound. In years past, you could type in a good list of keywords to Google and hit the I’m Feeling Lucky button.

Attempts to use LLMs for more than this fail. Often they do not fail in such an obvious way that the results are immediately discarded, which is where most of the danger resides.

I had thought that ‘pareidolia’ referred exclusively to the human tendency to see human faces everywhere – any time you see two dots or circles and a line below them, boom :) it’s a face. It can be triggered by rocks, clouds, shadows, uneven browning on a tortilla or a pancake.

It turns out, though, that pareidolia covers any kind of overactive pattern matching. Humans look for meaningful patterns all the time, without thinking about the search, and when something trips the right thresholds in our brain, we seize upon it. The result can be faces, voices, music or just a cloud that looks like a moose.

Here’s my thesis: the large language models (LLMs) and similar generative software processes that people currently refer to as “AI” – those are exceptionally well-tuned to produce patterns that will trigger threshold recognition in human brains. Not by accident – that’s the goal. They are pareidolia-circuit stimulators.

The problem is that LLM output is exactly as meaningful as any other kind of pareidolia. Every well-formed paragraph is a false-positive error.

And when people repeatedly mistake their overactive pattern recognition for reality, we call that a mental disorder: psychosis.
