It's not just "stupid" questions.

In my experience, most educational resources are either slightly too basic or slightly too advanced, particularly when you're trying to understand some new and unfamiliar concept. Lecturers, Youtubers and textbook authors have to make something that works for everybody, which means they might omit information you don't yet know while teaching you things you already understand. This is where LLMs shine, if there's a particular gap in your knowledge, LLMs can help you fill it, getting you unstuck.
