We'll all be grounded as a threat to National Security
Naaa, the least thing on the ground which has the most remote public importance, and all "No over my backyard" guys with or without sturdy umbrellas, will have electronic preprogrammed exclusion zones around their sensative ground based features. General aviation will be relegated to only the vast wilderness (haa, I'm safe here) and those little areas which occasionally exist between the exclusion zones.
All of this will happen because pilot skill will evolve to being a fly where the GX000 unit tells you, and don't think about what you are doing. The public will loose faith in our ability (averaged over the skill set of all pilots in general) to find our way, and deal with emercencies, without bumping into something which could be damaged. All human endeavours "dumb down" over the generations, so technology and exclusion zones must takeover public safety.
Case in point: In the last two weeks in Toronto, 14 pedestrians have been killed by vehicals while crossing the street (not counting injuries). How long will it be before Toronto starts erecting those pedestrian barricades, which I have seen on curbs in London and Hong Kong? Okay, well at least Toronto pedestrians had their freedom longer! (Until they, and in many cases the motorists, abused it with carelessness).
I own my runway, and aircraft with zero electrics and automated navigational capability will always be welcomed here!
