The app is optimized on the whole population, not on individual level. They even publish papers on global optimization.
These kinds of learning apps are destined to become mediocre over time.
The learning metric is so easy to capture, the learning content so easy to produce, yet no one has an individualized loop to make learning work well.
For example, I'd press "Training" on Duolingo, and would get nowhere. Same lessons all of the time. Bread and water.
Duolingo is laughably inefficient. I have an app I've made for myself to learn french, and it's amazing how little effort is required to make something 10x better. (I completed the french Duolingo tree and learned essentially nothing so I feel justified in saying that.) If you're learning french, let me know and I'll add you to the app.
