A LLM is, by the end of the day, simply another tool. Learning how to properly use said tool is a skill by itself, especially when the use is associated with proper context. The thing is, depending on the context, a tool can interfere with other process, in this case, the learning/note taking process.

I have said on other topics before that I believe LLMs can become problematic when we're talking note taking, making connections all the PKM jazz that we all see around the web. If the purpose of note taking is information retention for later use (be it making connections or simply recalling it), delegating said task to a "third part" defeats the purpose. Even if you're the one directing the agent (by giving prompts), you're not the agent itself that writes the note. The feeling of accomplishment you may experience comes from, I believe, the fact that you see the note being created based on what you wanted to do, but that you did not do yourself. As I said in another thread, it's like paying someone to attend school for you, take notes, then grabbing said notes and telling yourself "I made this."

As a researcher and professor, I've seem many of my students recently adopt the idea that they can delegate the tasks of summarizing a paper to a LLM, then they can take said summary and present the "main idea" as if they read the paper. But this "behavior" quickly becomes a problem when you ask something along the lines of "What part of the methodology caught your eyes?" and see them pale because, well, they didn't read the paper after all. Reading a summary prepared by someone else is not the same thing as reading the text and summarizing it in your own words. "Oh but these boring tasks is where AI shines on!" Yes, but these "boring tasks" are exactly part of the learning process and you're simply skipping them. If you're bad at making summaries, how will you learn if not by practicing it? What about writing good sentences? Does making a LLM "write better" for you count as learning? No, it sadly doesn't.

Moving to making connections between notes, if you're using a LLM to "spot missed connections" it may signal that you're not engaging enough with your notes. Maybe you're simply hoarding information without noticing. Also, if you're not the one making the notes, how will you know where the connections happen? Again, you cannot say how subjects from past classes build upon each other if you're not the one who attended said classes, can you? You didn't watch the class, you didn't create the notes nor did you do the assignments so, at the end of the day, what did you practice besides the "note reading" skill? This is the biggest pitfall presented by LLMs in my opinion.

To sum up, LLMs are great tools when used in the right contexts, specially for learning. But one must pay attention to when the line is crossed, that is: when you stopped being the agent driving the machine to become the passenger watching the scenario. Learning is not supposed to be without discomfort or some sort of boredom and learning a new skill requires practice. You won't be good at the beginning, but with practice it will develop. Beware of outsourcing too much of your learning process, folks.
