"On the back end, software programming tools and Internet-based services make it easy to launch new global software-powered start-ups in many industries - without the need to invest in new infrastructure and train new employees"

This quote by Marc Andreessen talks to the power of innovation and the internet in the contemporary world. He is suggesting that software programming tools and internet-based services have actually made it much easier than ever to introduce new worldwide software-powered start-ups in many markets. This indicates that entrepreneurs no longer need to invest in expensive infrastructure or train new staff members in order to get their business off the ground. Instead, they can use the tools and services available to them to rapidly and easily launch their business. This has actually opened a world of possibilities for business owners, allowing them to begin services in a variety of markets without the requirement for large investments.
