The study itself is entirely benign, and I'd actually accept it as a reason to eschew AI in an educational context. Their conclusion is basically "if you use an LLM to write an essay you tend to not retain the information as well", which is... Downright boring in how reasonable it is. Particularly given the converse observation I wouldn't have expected: if you are already familiar with a subject then using an LLM to write an essay can strengthen your understanding.
The "journal" this summary of the study was shared in is quackery, so I'm not surprised they distorted the findings.
