This is secretly advocating for the flat Earth
Or saying that the only global maps we should accept are ones projected onto spheres. Same thing for partial global maps above a certain size threshold (projected onto partial spheres).
I’m curious what that threshold is. Like how long do North/South roads need to be before there’s a non-trivial divergence towards the equator? How far do parallel East/West roads need to be before one is noticeably longer if measured from the same longitudes?
People know about what non-Euclidean means? Wow, do they also know about manifolds?
the secret is that all spaces are actually euclidean, due to the whitney embedding theorem.
(not really though. i just wanted to take my turn at improperly stating famous math results on the internet.)

I’m addicted to geodesics.
But i like walking into the same hallway 30 times!
Meh, planar geometry is for virgins, hyperbolic space go brrr
