The "building block" industry is already a decade+ old - its called AWS. Most development is already relegated to just doing the masonry between the blocks. "Building blocks" without operational support is useless. How do you provide support for some closed "building block" contributed by someone you will never meet? Open source solves this by making "building blocks" available to everyone freely. Clouds solve this by selling you a service and you don't worry about the code.
