Baby Rudin is a special textbook: it comes from a time when mathematics textbooks were not at all judged by their pedagogical value, but instead by their aesthetic appeal to mathematicians (a la Bourbaki).

If you actually want to learn analysis, there are a nearly infinite number of friendlier resources (e.g., Understanding Analysis by Abbott).

Learning to unpack difficult text on one’s own is a valuable skill. Research papers often require a similar amount of suffering, and at the frontier of knowledge, despite all the advances we’ve seen, LLMs seem to have absolutely no understanding or intuition. They are much better at things that have been expounded at length by humans before.

I would argue that if you’re going to use an LLM to make Rudin easier to understand, you are not learning how to absorb difficult material, nor are you learning analysis efficiently.
