I get your point ( with correction by @JoeAltmaier ) but with GPS and the like being the `new` tool, and with them needing new thought rather than continuation of the old "because we always did it that way"... I'd definitely go East in the future... along with changing calendars away from solar orientation ( Gregorian primarily ).
But as with most things involving the masses, this all falls into the category of why most use Metric versus Imperial, and why that is such a radical change to expect. Still, great to see a post questioning "up" ...
I get what you mean, if this were still a boat-based world. I am saying we are not in a boat-based world now. Our consciousness can re-orient.
Since we don't live in a boat-based world for the most part, it'd be more helpful to tend toward an orientation to a place where people have minds more often than people have ships. Part of why the world is the way it is, is because we don't allow our minds and the mental framework of the masses follow forward to an overall update to what in the world is actually worth orienting to.
So it's not change for change's sake. It's updating to be true to what we know, giving our minds the benefit of advancing onto a better framework.
Digital maps don't distort for curves. They just keep going with the surface of the planet. Remaining true to a boat-based world is a disservice to mind-having individuals.
BTW, GPS devices initially calculate their location in geocentric coordinates from the centre of the earth with the reference plane aligned to the equator. It is calculated from the orbital parameters of the satellites.
