Robotización (no es nuevo, pero ha mejorado sus prestaciones): Permite abaratar costes de mano de obra. La nube y el Big Data: permiten almacenar y analizar a un gran volumen de datos que se pueden intercambiar rápidamente. IA: permite a los robots interactuar entre ellos y ser autónomos. Simulaciones virtuales: para prever resultados y optimizar el funcionamiento de máquinas y programas. Realidad Aumentada (RA), para: formación de trabajadores. ofrecer instrucciones en tiempo real. Impresión 3D. Permite: elaborar prototipos. crear componentes. Ci...

The primary sector includes all economic activities where people obtain resources directly from nature. These resources are called raw materials (materias primas) because they will be transformed into other products later. Key Facts Importance:  It is the "starting point" of the economy because it provides the food we eat and the materials needed by factories.
