And yes, I can see a slight change in my own style, where I am using more "not" statements (negative propositions). While there are some folks with higher integrity and greater immunity to this infection, I am seeing that I am not entirely immune.
However, I have probably generated more dialog with AI over two years than in most of my years altogether. I have well over 7GB of content, of course, much of it the interlocutor -- but similar to how some adopt expressions and accents when imbued in various environments, alas, I have with AI, to whatever extent has bypassed my efforts to resist. The bright side, if it can be viewed such, is that I have developed an involuntary sensitivity to AI writing, often to the point of paranoia and false positives.
