Again, you don’t understand the value some people find in spaced-repetition algorithms. For example, in language-learning decks involving hundreds of cards, writing the cards may lead you to remember the word on a short-term basis, but you are likely to soon forget it. A flashcard app using spaced repetition will ensure that you see that card at the right intervals so that you can retain it until you definitively internalize the word from seeing it used in context in texts.
Understanding an argument and agreeing with it are not the same thing. I understand the premise and argument for spaced-repetition algorithms, but I do not agree that these algorithms provide a meaningful advantage over paper cards when you consider that paper cards must be written. The act of handwriting cards is an advantage paper cards have over software cards, which I believe more than offsets any algorithmic advantage the software cards have.
