No books before age 8 sounds like waldorf. They have this weird crazy belief that books shouldn't be introduced before the first adult teeth come out but at least they usually also shun digital in favor of more physical activities.
When we visited schools, we were also very surprised at how many schools encourage screen time. One of the most reputed school near us require each child to have an ipad at 6 years old. I'm completely against that. I see no value in introducing an addictive locked down device this early on. Instead, we chose a Montessori school that forbids electronic devices on campus except for the computing room where primary school children can go with a clear objective in mind (research, robotics project).
But, it was really surprising to me that that school is the exception and most highly ranked school have significantly more exposure to screens even at a very young age
