Which software carries out a set of operations on behalf of a user with a degree of independence and employs knowledge of the user's goals?

An ambient digital experience refers to a seamless and integrated user experience across devices and platforms but does not imply the software's ability to act independently on behalf of the user. This concept focuses more on the environment and context in which technology interacts with users rather than executing tasks autonomously.

Information of Everything is not a recognized term in technology or software fields. It does not describe a specific software type or functionality. Therefore, this choice does not pertain to a software that operates on behalf of the user or possesses the capability to work with user goals.

While virtual assistants, like Siri or Alexa, perform tasks for users, they typically require more direct input and guidance from the user to operate effectively. Unlike autonomous agents, virtual assistants lack the full degree of independence and decision-making capabilities that characterize an autonomous agent, which can act on its own based on user-defined objectives.
