Final answer:
The idea of humans continually improving upon improvements pertains to the ongoing process of technological advancements since the Industrial Revolution.
Step-by-step explanation:
The idea of humans continually improving on improvements refers to the concept that human progress, especially in terms of technological advancements, is an ongoing process. This is characterized by the enhancement of existing technology and the creation of new innovations that build upon previous inventions.
Since the beginning of the Industrial Revolution, there has been a significant increase in the pace of technological progress without apparent diminishing returns. Technological improvements have historically led to substantial gains in efficiency and output across various sectors of the economy.
One key aspect that may contribute to the sustained pace of innovation is that new technologies and inventions can have a wide application across an entire economy with a very low or even zero marginal cost.
Unlike a tool that can only be used by a single worker or a small group, an invention like the internet can be utilized by countless individuals, enhancing productivity on a large scale. In this way, technological innovation appears not only to build upon itself but also to spread benefits widely throughout society.
