Additionally, the increased production of goods and services can generate higher sales, resulting in higher incomes for businesses and their employees. This increase in incomes and profits not only benefits the businesses themselves but also contributes to economic growth and development.

The boost to the economy also extends to other sectors, as businesses supplying inputs to the production process also experience increased demand. Overall, the production of new and better goods and services using new technology contributes to a more vibrant and dynamic economy.
