Wasn't the first rule of flash cards not to memorize things which you don't already understand? Generated (LLM?) flashcards might result in you missing out on the whole "understanding the text and breaking it down into flashcards" part of the process - which seems rather important.

Yes, it's meaningless if the topic is mostly unknown to the learner. But that's not the goal of flashcards - the goal is to first read the text, and then reinforce what you learned with bite-sized questions/answers.

Everyone learns differently, I always found flashcards to be incredibly useful and entertaining.

Michael Flynn is a legendary name in Computer Architecture; his taxonomy - https://en.wikipedia.org/wiki/Flynn%27s_taxonomy

His computer architecture book (listed here - https://news.ycombinator.com/item?id=42621236) is still one of the best focusing on principles and design and hence timeless. The language is succinct and very focused on explaining things. I have found it much better than many popular textbooks on computer architecture.

As an example, the submitted article is just 18 pages (pdf) and yet manages to highlight all the major points; a absolutely beautiful overview.

This almost guaranteed to be a waste of time for others, though, because you created them for yourself, perhaps less so for you.

Learning isolated facts via flashcard give you the illusion of learning something. Most likely, when it comes time to apply it, it will not surface.

I got very positive feedback from students preparing for high school keystone exams (given that it can generate questions from a given online resource / PDF) so I'm pretty happy about that!
