g. devices) using innovation by taking an input, changing it according to the system's usage, and then producing an result are referred to as technology systems or technological systems. The simplest type of innovation is the advancement and use of fundamental tools. The prehistoric discovery of how to control fire and the later Neolithic Transformation increased the available sources of food, and the development of the wheel helped humans to travel in and manage their environment. Developments in historic times, including the printing press, the telephone, and the Web, have actually decreased physical barriers to communication and allowed humans to communicate freely on a worldwide scale.
It has helped establish more advanced economies (consisting of today's international economy) and has permitted the increase of a leisure class. Numerous technological processes produce undesirable spin-offs called contamination and diminish natural resources to the hinderance of Earth's environment. Innovations have actually always affected the values of a society and raised new questions in the principles of technology. Examples consist of the rise of the notion of effectiveness in regards to human efficiency, and the challenges of bioethics. Philosophical disputes have actually occurred over using innovation, with disagreements over whether innovation enhances the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary motions slam the pervasiveness of innovation, arguing that it harms the environment and pushes away individuals; advocates of ideologies such as transhumanism and techno-progressivism view continued technological development as helpful to society and the human condition.
