This is no longer always true.
Technologies are increasing in power exponentially and transforming businesses and industries overnight. Firms such as Kodak, Blockbuster, Borders, the Yellow Pages Group along with industries such as newspaper and music publishing have been transformed already.
Advanced technologies such as the internet of things, cloud computing, big data, robotics, drones and genomics are preparing to turn the retail, energy, healthcare, financial services, manufacturing and agricultural industries on their heads.
In addition, new technology enabled business models represented by firms such as Uber, Airbnb and a slew of well financed sharing economy startups are challenging the travel and accommodation industry today and most other sections of the economy tomorrow.
