Mechanization
Machines replacing muscle as the power behind work.
The word belongs to a family, and the family has a rule. A technology gets an -ation noun when it stops being a thing you buy and becomes a change in how the work is done. Nobody says tractorization, because a tractor is a purchase. Mechanization is what happened to farming once the tractor arrived and animals and men stopped being the power source.
Each member of the family names a different substitution. Electrification replaced steam and line shafts with electric drive, and the plants that gained from it were the ones that rebuilt their layouts rather than bolting motors onto old machines, which took roughly thirty years. Containerization replaced break-bulk cargo with one steel box, and ships, docks, trucks and rail all reorganized around a single dimension. Computerization moved ledgers and calculation into machines, and is the one automation gets confused with, because a faster ledger is still a ledger someone maintains.
Above them sit the general terms. Industrialization is the whole economy moving from craft and farm to factory. Standardization sits underneath most of the rest, since nothing scales until the interface is fixed. The steel box worked because every port agreed on the same dimensions.
Across languages
Polish mints an abstract noun for any infrastructure rollout, so gazyfikacja and telefonizacja are ordinary words. English never did. Building out gas supply to households is gas network expansion or mains gas connection, a phrase and not a noun, and gasification means something else entirely in chemistry. English kept the -ation only where the rollout changed how work was done. Gas reached houses and heated them, and no operation changed, so no word was needed.
It runs the other way too. Where the conversion happened in English first, the root travels and each language fits its own ending. Containerization became konteneryzacja, conteneurisation, contenerización, Containerisierung. Computerization did the same, except in French, which had already refused the word computer in favour of ordinateur and ended up with informatisation instead, meaning something wider.
Automation is the current member of the family, and it passes the test. It is not a product anyone buys. It is a conversion applied to how the work runs.
