Final answer:
It is generally false to say technology is futile, as it encompasses a wide range of applications that facilitate daily life and has a significant impact on efficiency, communication, and economic sustainability.
Step-by-step explanation:
The question on whether technology is useless or not is fundamentally subjective and dependent on context. However, using the broad definition of technology as the application of science to address the problems of daily life, it is evident that technology is far from futile. For instance, agricultural advances, the creation of computing devices, and the pervasive use of smartphones are all testaments to the utility of technology in improving human life.
Moreover, the efficiency of a simple machine never being 100% due to friction is a true statement, showing the practical limitations in the use of technological tools.
Similarly, the statement regarding refraction being useful in fiber optic cables for transmitting signals is true, illustrating the critical role physics plays in the development and functioning of advanced technologies.
Lastly, technology has allowed for the production of goods that can be reused, giving companies that invest in development a competitive edge. This emphasizes how technology is intertwined with economic growth and sustainability.
