The increase of dexterity of workmen implies they are able to produce, in the same time, more products. This means this means they can produce more goods.
The saving of time allows the workman to be more concentrated on the production of goods, indeed this enables an increase of production.
Proper machineries are faster than workman in produce goods, so they could replace many workmen and work without stopping.
