Great point, Roger.
It kind of boils down to having enough basic knowledge to know when what the electronics are telling you don't make sense. If all a kid knows how to do is punch numbers into a pocket calculator, and doesn't actually know multiplication tables, then when he/she makes a fat finger mistake or misplaces a decimal point, they'll have no clue that their total is way off.
All too often we read about people who blindly follow their car nav systems with humorous or tragic results.
Yes, electronics are a great tool, but it should never be the only one in your toolbox.
