Automation is the use of technology to execute tasks with little or no human effort, from simple rules like auto-sending invoices to AI-driven processes that read documents, answer clients, and make routine decisions. The goal is not replacing people but freeing them from repetitive work: a Marrakech restaurant that automates reservation confirmations and supplier orders lets its staff focus on guests. Modern AI dramatically widens what can be automated, reaching tasks involving language, images, and judgment that once required humans.
