I do think the general purpose screens of today are doing a disservice for education. There are too many possible distractions a child isn't prepared to resist yet. But it could enable more advanced workflow for personalized learning.

I think the k-shaped economy where some people are financially succeeding while the rest go through hardship is a reflection of a k-shaped education system where those who are able to ignore the distractions and succeed are doing well. The top of the k can use more edtech as they just need tools for further educational attainment. Things modern edtech can bring. The bottom of the k has different needs.
