It’s not thinking. It’s just spicy autocomplete; having ingested most of the web, it “knows” that what follows a question about the meaning of a phrase is usually the definition and etymology of that phrase; there aren’t many examples online of anyone asking for the definition of a phrase and being told “that doesn’t exist, it’s not a real thing.” So it does some frequency analysis (actually it’s probably more correct to say that it is frequency analysis) and decides what the most likely words to come after your question are, based on everything it’s been trained on.
But it doesn’t actually know or think anything. It just keeps giving you the next expected word until it meets its parameters.
Because this here is for support. That there is for evangelism.
