What do we call the tools and innovations that facilitate interactions in society?

The term that best describes the tools and innovations facilitating interactions in society is "technologies." This encompasses not only machines and devices but also various systems and methods that enhance communication, transportation, and engagement among individuals and groups. Technologies essentially serve as a bridge, connecting people across distances, increasing efficiency, and transforming the way we interact.

In contrast, "resources" typically refer to raw materials or assets that can be utilized for economic production or development but don’t specifically focus on interactions. "Artifacts" often denote objects made or used by humans that hold cultural significance, but they do not inherently signify the tools for interaction in a broader context. "Inventions," while relevant to the creation of new technologies, represent specific innovations themselves rather than an overarching category that encapsulates all tools and innovations aiding societal interactions. Thus, "technologies" provides a comprehensive and accurate framework for understanding these interactions.
