This is false, it is trivial to find humans with 99%+ accuracy[1] and there is a well-known service with 99%+ accuracy when analyzed by 3rd parties with no affiliation.[2]

As we see above, this is just guessing in an unscientific way. :) It's important to be rational! We all agree on that. :)
FWIW it did used to be true that the 3rd party services were junk. And I don't support the idea of humans just winging it when there's consequences. The case we're in is about the most mundane and consequence-free, the vast majority of us use AI daily and we're commenting on an internet aggregator that is aggregating a blog article.
