I was thinking the same thing. Currently all my cards try to all follow the same pattern, making it necessary to really remember at based on differences between them. (For example, I would never ask "What happened in 1914?" but instead just "1914" and have "Start of WWI" on the back, as a reversible card). LLMs could take such cards and provide the user with an endless stream of questions: What year did WWI begin? What happened in 1914? Which event took place in 1914? And so on. For vocabulary this might of course be even better when the word/phrase itself will always be contextualized in practice.
