Disagree. AI text generation is going to ruin stylometric analysis as anonymous online communities get spammed by ever increasing amounts of automated content based on inputs learned from random subsets of users. A good, helpful AI generation bot is an easy way to harvest up-votes on content platforms like Reddit or HN and subsequently manipulate content.

good point and I agree with the effect, but I'm not sure about the scope. I'm not sure if it will be enough noice to equalize it.

Something else that comes to my mind: Lot of people on HN (me included) share rather personal stuff here. Everything I ever said with this account should (in theory) fall in a consistent picture. But those bots are not there to mimic that. They have other purposes (some of which you already mentioned).

>Not because of credentials or personal data, but the things we say and the way we say them online. These things will be enough to link personal accounts and alt-accounts.

Are you basing this on writing-style analysis?

yes and more. Not only form, but also content.
