The interesting thing is that chatgpt can absolutely profile you and profile you well in ways you probably did not consider ( ask for stylometric fingerprint if you think you are ready to go down that particular rabbit hole ). I don't say it very often, because I simply dislike advertising almost to the degree of certain comedian, but if there ever was a clear mismatch between what the tech can do AND what it actually is being used for, it is llms.

You can ask it to make guesses about your location, your educational background, etc, based on what you provided in the past. Illuminating.
