I’m conflicted on this rush toward data on just about every part of my daily life. While it’s good to know if #4 cylinder is showing signs of wear, it isn’t necessarily good to know the whereabouts of an airplane or its pilot; that information has all sorts of implications. So it may be the answer lies in just what data is collected; the kind of data may clearly define purposes.
ADS-B is data enough, my flight planning/flight management software nosy enough to make the time in my traveling airplane a bone for all the geeks to chew. That makes time in my no-electrical-system, steel tube, dope and fabric bug smasher pure delight.
