This lecture explores the historical development of human techniques, from the acquisition and manufacturing of materials to the construction of housing and tools, as well as the impact of machines and energy sources on society. It delves into the classification of machines, the evolution of technical objects, and the challenges posed by the depletion of fossil fuels and climate change. The presentation covers various scenarios for the future, ranging from a techno-explosion to energy descent, and discusses the potential consequences of each. Through an analysis of different energy futures and societal responses, the lecture provides insights into the complex relationship between technology, sustainability, and human welfare.
