I guess it depends on how young we're talking when we say "children". It's all up to each individual parent, but personally, for the early years, I think there is plenty enough to see, learn and experience in the physical and social world that there's no need to introduce the virtual world. Nor do I think that learning about phones, the internet, etc. at a slightly later age is a negative in any sense.
