Teachers, however, are not and will never be replaceable—and especially for younger children, some things can never be digitized. "We build in a lot of sensory experience—we get outdoors and see, smell, hear real things," says Great Barrington Rudolf Steiner School teacher Nancy Franco. "We're human beings together on this planet—connecting to that is crucial. People who are concerned about getting children into technology as early as possible are forgetting that by the time these kids are in high school, they'll probably be working with entirely new technology. And we find that with a solid real world foundation, kids adapt to keyboards and screens almost instantaneously. We believe in approaching technology in a very conscious way."
