Just as the community adopted the term "hallucination" to describe additive errors, we must now codify its far more insidious counterpart: semantic ablation.
Semantic ablation is the algorithmic erosion of high-entropy information. Technically, it is not a "bug" but a structural byproduct of greedy decoding and RLHF (reinforcement learning from human feedback).
During "refinement," the model gravitates toward the center of the Gaussian distribution, discarding "tail" data – the rare, precise, and complex tokens – to maximize statistical probability. Developers have exacerbated this through aggressive "safety" and "helpfulness" tuning, which deliberately penalizes unconventional linguistic friction. It is a silent, unauthorized amputation of intent, where the pursuit of low-perplexity output results in the total destruction of unique signal.
When an author uses AI for "polishing" a draft, they are not seeing improvement; they are witnessing semantic ablation. The AI identifies high-entropy clusters – the precise points where unique insights and "blood" reside – and systematically replaces them with the most probable, generic token sequences. What began as a jagged, precise Romanesque structure of stone is eroded into a polished, Baroque plastic shell: it looks "clean" to the casual eye, but its structural integrity – its "ciccia" – has been ablated to favor a hollow, frictionless aesthetic.
We can measure semantic ablation through entropy decay. By running a text through successive AI "refinement" loops, the vocabulary diversity (type-token ratio) collapses. The process performs a systematic lobotomy across three distinct stages:
Stage 1: Metaphoric cleansing. The AI identifies unconventional metaphors or visceral imagery as "noise" because they deviate from the training set's mean. It replaces them with dead, safe clichés, stripping the text of its emotional and sensory "friction."
Stage 2: Lexical flattening. Domain-specific jargon and high-precision technical terms are sacrificed for "accessibility." The model performs a statistical substitution, replacing a 1-of-10,000 token with a 1-of-100 synonym, effectively diluting the semantic density and specific gravity of the argument.
Stage 3: Structural collapse. The logical flow – originally built on complex, non-linear reasoning – is forced into a predictable, low-perplexity template. Subtext and nuance are ablated to ensure the output satisfies a "standardized" readability score, leaving behind a syntactically perfect but intellectually void shell.
The result is a "JPEG of thought" – visually coherent but stripped of its original data density through semantic ablation.
If "hallucination" describes the AI seeing what isn't there, semantic ablation describes the AI destroying what is. We are witnessing a civilizational "race to the middle," where the complexity of human thought is sacrificed on the altar of algorithmic smoothness. By accepting these ablated outputs, we are not just simplifying communication; we are building a world on a hollowed-out syntax that has suffered semantic ablation. If we don't start naming the rot, we will soon forget what substance even looks like.
This is made worse because of how illiterate westerners are too. If you can't edit the output of a chat bot, you can't tell how shit the output is. Its like when you see a social media post and its clearly written by ai cause theres incomplete sentences, weird capitalizations, the over use of lists that could just be items separated by commas, blatantly incorrect imformation etc. Its maddening. I've received emails from new businesses trying to put themselves out there and its all ai slop. Theres a race to the bottom in our societies. Who can be the most lazy; who can think the least; who can put in the least amount of effort and still get everything they want. Its like those studies where they put people in an empty room, theres nothing but a table, chair, and a button on the table. The button shocks you. And people will sit there the whole time shocking themselves instead of being alone with their thoughts. Why are westerners, or maybe this is a global phenomenon, so afraid of their own minds, thoughts, feelings, boredom? Do people really just want to be little pleasure piggies? Press button gimme slop. Do people not like learning? Cause thats sad if they don't.
They don't like learning because at some point in their past, learning got them in trouble, either with a bully in school or some authority figure. Anti-intellectualism is the dogma of American secular religion and it is strictly enforced by its adherents.
