socio-economic development. The first wave was the Agricultural Age with wealth defined as ownership of land. In the second wave, the Industrial Age, wealth was based on ownership of Capital, i.e. factories. In the Knowledge Age, wealth is based upon the ownership of knowledge and the ability to use that knowledge to create or improve goods and services. Product improvements include cost, durability, suitability, timeliness of delivery, and security. Using data, in the Knowledge Age, 2% of the working population will work on the land, 10% will work in Industry and the rest will be knowledge workers. Knowledge work in the 21st century Davenport (2005) says that the rise of knowledge work has actually been foreseen for years. He points to the fact that Fritz Machlup did a lot of the early work on both knowledge as well as knowledge work roles and as early as 1958 stated that the sector was growing much faster than the rest of the economy with knowledge workers making up almost a third of the workforce in the United States. "According to the Organization for Economic Co-operation and Development (1981), by the beginning of the 1970s around 40 percent of the working population in the USA and Canada were classified to the information sector, whereas in most other OECD countries the figures were still considerably lower." As of 2016, an average of 1.9 million knowledge worker positions had been added every year since 1980, more than any other type of role. Tapscott (2006) sees a strong, on-going linkage between knowledge workers and innovation, but the pace and manner of interaction have become more advanced. He describes social media tools on the internet that now drive more powerful forms of collaboration. Knowledge workers engage in peer-to-peer knowledge sharing across organizational and company boundaries, forming networks of expertise. Some of these are open to the public. While he echoes concern over copyright and intellectual property law being challenged in the marketplace, he feels strongly that businesses must engage in collaboration to survive. He sees on-going alliance of public (government) and private (commercial) teams to solve problems, referencing the open source Linux operating system along with the Human Genome Project as examples where knowledge is being freely exchanged, with commercial value being realized. Palmer (2014) researched knowledge worker productivity and work patterns. Part of this research has involved the analysis of how an average knowledge worker spends
