Only the paranoid survive :)
Schumpeter, a former Austrian Minister of Finance and Harvard Business School professor, expressed the view in his classic work Capitalism, Socialism and Democracy that the essence of capitalism is the process of "creative destruction" - the perpetual cycle of destroying the old and less efficient product or service and replacing it with new, more efficient ones. Andy Grove took Schumpeter's insight that "only the paranoid survive" for the title of his book on life in Silicon Valley, and made it in many ways the business model of globalization capitalism. Grove helped to popularize the view that dramatic, industry transforming innovations are taking place today faster and faster. Thanks to these technological breakthroughs, the speed by which your latest invention can be made obsolete or turned into a commodity is now lightning quick. Therefore, only the paranoid, only those who are constantly looking over their shoulders to see who is creating something new that will destroy them and then staying just one step ahead of them, will survive.
