It may not be to your taste, and you certainly may not want to make time, but if — double negative! — both should prove not to be the case, I recommend reading Vernor Vinge’s Rainbows End, which can be bought at your preferred seller of books.
Ironically, Vernor made it available for free on a website for a very long time, but no longer.
