Happy to disagree here. I am hopeful that students get apps which provide them with - fast feedback loops - better adjustment to their learning speed - more patience - gamification - oppurtunity to ask endless questions

Of course, only as an addition to the current mix. For math problems, this will be easier than for other contexts.

I like text books for pop science or really hard things - like university level education. But I am surprised to see them as an option for basic education.
