What are the following impacts of the Industrial Revolution are commonly agreed? 1. The most striking change in the character of work is the extraordinary rise of professional and technical employment and the relative decline of skilled and semi-skilled workers; 2. Today education has become the basis of social mobility, especially with the expansion of professional and technical jobs, and even entrepreneurship requires a higher-education background; 3. Knowledge is no longer the source of invention and innovation.

The impacts of the Industrial Revolution that are commonly agreed upon include:

1. Change in the Nature of Work: The Industrial Revolution led to a significant shift in the nature of work. There was a marked increase in professional and technical employment, while the demand for skilled and semi-skilled workers declined. This was due to the mechanization of many processes, which reduced the need for manual labor.

2. Importance of Education: The Industrial Revolution also emphasized the importance of education. With the rise in professional and technical jobs, education became the basis for social mobility. Even entrepreneurship started requiring a higher-education background as businesses became more complex and technology-driven.

3. Role of Knowledge: Contrary to the statement, knowledge continued to be the source of invention and innovation even after the Industrial Revolution. In fact, the importance of knowledge increased as industries became more technology-oriented. The revolution led to a surge in scientific discoveries and technological innovations, all of which were driven by knowledge.

Therefore, while the first two impacts are commonly agreed upon, the third one is not. Knowledge has always been, and continues to be, the driving force behind invention and innovation.
