Just so I understand: You're totally cool with ChatGPT being trained on everything you've ever written and also logging everything you ask, but stylometric analysis of that log is your bridge too far?
IMO - the problem is the inability to opt out of anything AI going forward.
We thought the singularity was when AI is smarter/developing faster than humans - but the singularity has already been passed ; you cannot opt out of anything AI-mining your every-thing.
