    Yes, it's a strange irony. We work to make navigation simpler, but then it 
    becomes so simple that any fool can do it. It's interesting to note that this 
    also applied to navigation historically. I was listening to a museum 
    interpreter recently describing the chip log. This, of course, is a simple 
    bit of technology, perfected only in the 18th century, that lets us measure 
    our vessel's speed scientifically and thus improves the DR. The interpreter, 
    who had done a small boat circum-navigation, commented that anyone with 
    significant sailing experience soon reaches the point where they can estimate 
    speed easily and accurately without resort to hardware so the chip log seems 
    superfluous. But that's not the point. The chip log could be used properly 
    and yield accurate results even in the hands of novice seamen once they had 
    been taught. The tools of scientific navigation exist to make us all experts 
    without requiring expertise. 
    And I can't help getting a little laugh from the auto-signature appended by 
    your iPhone. That little thing is sending your email AND tracking your 
    position better than any of us could ever have hoped for twenty years ago.
