"According to this hypothesis, the gesture was a secret sign used to recognize masonic followers each other"
I have never heard this verbiage before... Did an AI write this? Or, can someone explain to me how "used to recognize followers each other" is grammatically sound?
I recall when young, people were commenting on how most media came from centralized locations. That with newspapers, and then radio, and now TV, pronunciation was moving towards being less regionalized, diverse, yet also that the choice of words to use, the synonyms to use, was changing.
I also recall the same being said for a variety of things, such as spell checkers, and grammar checkers used in wordprocessors. Some grammar was "OK", but other forms were being pushed by (most especially) earlier wordprocessors, with grammatically valid text being marked with that wavy underline.
Now we have AI.
My point?
Kids are going to be raised in a world with AI. If it spends a decade or more spewing blather such as this, an entire slew of people will grow up, from 10 to 20 years old, 15 to 25 years old, learning to cobble together sentences in this sort of way.
Not only will they read it, but "helpful" assistants will change their normal prose, into this gibberish.
So I'm sorry mkl, it sort of will be grammatical. And no, I'm not happy about it.
I think you know an AI didn't generate the sentence because it's ungrammatical.
The publication in question (Acta Biomed) is oriented around "mainly national and international scientific activities from Mediterranean and Middle Eastern countries", so there's a reasonable chance none of the the authors speak English as a first language. This in no way excuses bad editing—the journal publishes in English, after all.
