In the maximal case where bots are indistinguishable from humans, by definition the odds of failing the Turing test are 50/50. A coin flip per comment. Yeah, I can put up with that.
Realistically, I don't think I will ever start regularly failing it. Go ahead, call it arrogance or hubris or whatever. I've looked at the originality and predictability metrics on a large corpus of my online comments. Let's just say, you won't be replacing me with gpt-3 or similar.
