The interesting thing is that these days the maps people most use are digital ones. They can be updated instantly for everyone who uses them. But, even in that world you have problems.

In many countries it's a legal requirement that the maps reflect the country's definition of its borders. That means that in some cases Google Maps has 3 versions of a map, the one shown to users in country X (say India), the one shown to users in country Y (say China) and the one shown to users in the rest of the world, where the border is marked as disputed.
