Is a text either 0% or 100% AI-written? The debate over AI authorship attribution

Afinetheorem · x · 2026-09-09

A counterintuitive claim circulated: the percent of a text that is AI-written can only be 0% or 100% — "a text that is 20% AI is like a gallon of milk that is 20% spoiled."

Another writer pushed back: if you merely use AI for spell and grammar checks that change 3% of the words, would you still call it "AI written"? The exchange highlights the ambiguity of AI authorship attribution and detection, an ongoing fault line in the AI community.
