I worry about the day when if a guy loses his phone, he becomes a useless fool, unable to do anything. Technology is great but you still need to understand what the numbers mean and be able to do a quick back of a doughnut box calculation that is in the ballpark. It is like people who can do the ohm's law math on their phone but they are still confused about why there is a red light on their ground bus bar.
