Most current industry leaders owe their existence beyond basic competencies and resources to a strong competitive advantage from early adoption of systems engineering and statistical methods for industrial production that powered much of the post WW2 economy. These manual systems and methods accelerated global trade, extraction, logistics, manufacturing and scaling efficiencies, becoming computerized over the last half-century.
The computer systems were initially highly complex and very expensive, though resulted in historic business success such as American Airlines’ SABRE in 1959  and Walmart’s logistics system staring in 1975 , which helped Walmart reach a billion USD in sales in a shorter period than any other company in 1980.
As those functions previously available to only a few became productized and widely adopted globally, the competitive advantage began to decline. The adoption argument then changed from a competitive advantage to an essential high cost of entry. When functionality in databases, logistics and desktops became ubiquitous globally the competitive advantage was substantially lost, yet costs continued to rise in software while falling dramatically in hardware, causing problems for customers as well as national and macro global economics. In order to achieve a competitive advantage in IT, it became necessary for companies to invest heavily in commoditized computing as a high cost of initial entry, and then invest significantly more in customization on top of the digital replicas most competitors enjoyed.
The network era began in the 1990s with the commercialization of the Internet and Web, which are based on universal standards, introduced a very different dynamic to the IT industry that has now impacted most sectors and the global economy. Initially under-engineered and overhyped for short-term gains during the inflation of the dotcom bubble, long-term impacts were underestimated as evidenced by ongoing disruption today causing displacement in many industries. We are now entering a new phase Michael Porter refers to as ‘the third wave of IT-driven competition’, which he claims “has the potential to be the biggest yet, triggering even more innovation, productivity gains, and economic growth than the previous two.” 
While I see the potential of smart devices similar to Porter, the potential for AI-enhanced human work for increased productivity, accelerated discovery, automation, prevention and economic growth is enormous and, similar to the 1990s, while machine intelligence is overhyped in the short-term, the longer term impact could indeed be “the biggest yet” of the three waves. This phase of IT-enabled competitiveness is the logical extension of the network economy benefiting from thousands of interoperable components long under development from vast numbers of sources to execute the ‘plug and play’ architecture many of us envisioned in the 1990s. This still emerging Internet of Entities when combined with advanced algorithmics brings massive opportunity and risk for all organizations in all sectors, requiring operational systems and governance specifically designed for this rapidly changing environment.
