Most other AI guided systems (which are basically all offshoots of large language models in some way) are used as tools by people who are already familiar with the subject matter at the AI manipulates, which means that they can essentially fact check it.

Using the AI as a teacher implies that you are a student with virtually little to no understanding of the subject matter, which means you have no way to sanity check if the AI messes up and gives you incorrect information. You could end up with a deeply flawed understanding of the actual domain you wish to become an expert in.
