I don't think mkramlich was meaning to imply otherwise, because the relevancy of parents' involvement doesn't just apply to technology. Engaged parents who involve their kids in engine rebuilding or animal husbandry or child rearing or anything else that requires years, effort, and guidance to master are most likely are in the top 1% in terms of intellectual development.

Technology and computers wasn't my mom's hobby or profession (she's actually a seamstress -- and I learned the basics of sewing from her) so it wasn't like she was introducing me to her interests; however, when my son gets older (out of diapers), I plan on spending time with him teaching about my major interests and learning new things with him that's he's interested in, independent of what that may be.
