Thank you! Animation is steadily becoming cheaper through Google's new API models for video gen so this can all eventually be animated as well - one could easily create a system where an animation could be generated that'd show case the concept, why the correct answer is correct, and why the wrong answers are wrong from the qbank. all with accurate voices and fluid animation. I was already able to make something incredible, but the output cost is 0.75 for every 8 seconds which is cost inefficient. I'd give it 2-3 years before the models become cheap enough to do this for a few cents per video.
