User experience design (UX, UXD, UED or XD) is the process of enhancing user satisfaction with a product by improving the usability, accessibility, and pleasure provided in the interaction with the product.
Enhancing user satisfaction is not about making users lazy. It is about facilitating the way we use product or services to be as efficient as possible to its purpose.
Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the ability to do things well, successfully, and without waste.
Reducing the time and effort to accomplish something, prevents mistakes and gives us the opportunity of using that time to do a second task, whatever it is.
So it is more in terms of being able to achieve more tasks because there are thoughtful decisions behind the overall design, versus achieving less because the way to accomplish the tasks is unintuitive and might end up in conflicts.
