Technology refers to artifacts created by humans to meet needs and wants through purposeful application of knowledge and experience. It involves both physical machines and methods used to create them. While often referring to modern computers and devices, technology more broadly encompasses any means used to organize human activity, like democracy as a social technology. People judge new technologies based on their impacts on health, well-being, economies, and environments in their communities. Modern technology has solved many problems but also risks replacing human relationships and overdependence if not developed and distributed responsibly.
