Agreements You Can Only See When They Break

Dates, characters and connectors are the small print of daily life, and each has its own long argument behind it.

Write a date as three numbers and you have created an ambiguity that has caused an extraordinary quantity of trouble. Different parts of the world settled on different orderings, each perfectly sensible internally, and the collision produces errors that are invisible for most of the month and then suddenly are not. The unambiguous ordering exists, and it is agreed, and it is written down, and it wins slowly wherever machines have to read what people wrote, because machines are less forgiving than readers about which number is the month.

Character encoding tells a similar story with higher stakes. For a long time the way text was stored depended on assumptions about which language you were writing, and moving text between systems meant hoping the assumptions matched. When they did not, names came apart into rubbish. The eventual agreement on a single scheme capable of representing the writing systems of the world was among the most quietly civilising acts of the era, because it meant a person's name could travel across systems intact, which is not a technical nicety but a matter of dignity.

Plugs are the standard that never converged, and they are instructive precisely because they failed. Different countries arrived at different pin geometries and voltages early, built everything around them, and then found the cost of switching prohibitive forever after. The traveller with a bag of adaptors is carrying the physical residue of a coordination failure that happened before anybody involved was born. It is a reminder that standardisation is not inevitable. It happens when it happens, and where it does not happen in time, we live with the seams.
