The document discusses generational differences in attitudes towards the importance of software as a competitive advantage between Microsoft, Google, and Facebook.
Microsoft historically viewed software as its primary competitive advantage and developed software for many markets. Google chose open source software and focuses on infrastructure efficiency rather than proprietary software. Facebook believes infrastructure software is non-differentiating and runs primarily on open source and publicly available software. Perceptions are evolving to recognize that software is less of a means to differentiate as it becomes more standardized and commoditized.
