Why do Waldorf schools suggest limiting media?

Waldorf teachers appreciate that technology must assume a role in education, but at the appropriate developmental stage, when a young person has reached the intellectual maturity to reason abstractly and process concretely on his or her own, ​which is at around the age of 14. Society might challenge this principle, as many young children are well able to complete sophisticated tasks on a computer; the Waldorf perspective is that computer exposure should not be based on capability but on developmental appropriateness. While many applaud adult-like thinking in young children, we observe that a child’s natural, instinctive, creative and curious way of relating to the world may be repressed when technology is introduced into learning environments at an early age.
