The concept of a "Knowledge worker" is relatively new, yet still has undergone numerous changes, as depicted in the 'New Knowledge Worker' graphic. Before the 20th century, manual labor was the be all and end all industry. However, along with greater developments following the industrial revolution, man has been able to delegate these tasks to manmade machinery and thus, free up an industry for advanced thought and new kinds of jobs.
The knowledge industry has been crucial to the latter half of the 20th century and invaluably vital to the 21st century. The infograph on the new knowledge worker depicts the 21st century worker with smartphones, tech accessories and innovative designs that have defined an entirely new realm of industry.
