Teach them to read real books, on paper, by real authors. Given them lots of unstructured time in nature with other children, with a watchful parent nearby (this requires investment of a parents' time, but I can't think of a better investment).
Sorry, mine wasn't a plain boomer rant, there are plenty of "real" books I would never let my child read. Most classics are very mature and talk very vividly about violence, death, sex and atrocities. Children should be exposed to nuanced stuff that isn't dumbed down, it's just that these nuanced things should be in the realm of a child, leaving the more mature stuff to older people. A book talking about the friendship between two children in a complex way is cool and good, a book talking about the friendship between two drug addicts might be more suitable to someone who knows a bit more about life.
