Technology separate from Work and Education

In Waldorf School in Silicon Valley, children from "employees of Silicon Valley giants like Google, Apple, Yahoo and Hewlett-Packard." go to school there. This surprises me but to a point at which i can understand where they are coming from. The employees that work at those companies came from a generation where technology had no connection with education. With the tools they had at their schools they were creative enough to create companies like google, apple, and yahoo. They believe that using technology in education  could create tunnel vision. They only stated that they rejected technology in education in grammar school, which only consists of elementary schools. Elementary school is a period where a child's mind is developing rapidly, so they appose the idea of technology in  a children's brain development period. Thus telling us that they think technology can affect a child's brain development negatively.
