Technology refers to the application of tools and methods to achieve a goal or solve a problem. It can be as simple as a monkey using a stick to obtain food or as advanced as sending spacecraft into space. The level of technology used is often used to classify human civilizations, such as the Bronze Age when humans started using bronze tools. While technology brings benefits like food and information, it also carries risks like weapons that can kill or data that can be used to manipulate behavior. As technology shrinks to the nano scale, it provides new opportunities for healing but also new dangers if misused in warfare. Advanced technology highlights humanity's distinction from animals but also increases our responsibility for its impacts.
