LLMs, by design, are peak Duning-Kruegers, which means they can be any good of a study partner for basic introductory lessons and topics. Yet they still require handholding and thorough verification, because LLMs will spit out factually incorrect information with confidence and will fold on correct answers when prodded. Yet the novice does not posses the skill to handhold the LLM. I think there's a word for that, but chadgbt is down for me today.
Furthermore, forgetting curve is a thing and therefore having to piece information together repetitively, preferably in a structured manner, leads to a much better information retention. People love to claim how fast they are "learning" (more like consuming tiktoks) from podcasts at 2x speed and LLMs, but are unable to recite whatever was presented few hours later.
Third, there was a paper circulating even here on HN that showed that use of LLMs literally hinder brain activation.
