I know stylometry is a thing, but is it good enough to fingerprint you according to what you know or talk about? What about in the future as NLP advances?

For a historic example, '...although Newton's solution was anonymous, he was recognized by Bernoulli as its author; "tanquam ex ungue leonem" (we recognize the lion by his claw).' https://en.wikipedia.org/wiki/Later_life_of_Isaac_Newton#Ber... I am guessing the proof techniques were so hard/original that Bernoulli concluded only Newton could've come up with it at that time.

Likewise, I would assume there's only a handful of people in the world who have this level of expertise on online anonymity. So do you then have to keep this expertise completely isolate to one particular anonymous account to avoid being correlated?

My concern applies to knowledge that isn't particularly world class too, as long as it's in a unique combination. I guess in some sense what we know makes us who we are so it's hard to avoid being "identified" that way without splitting your personality?
