Cable Green on Open Educational Resources

This locking down of information stifles innovation. Having no access to research across a scientific field means slower progress and expensive redundancies in different organizations doing the same work. With course materials having such high cost, keeping textbooks up to date either costs schools too much or students too much, and this makes education less accessible, which means we get fewer qualified people growing up into important fields. Pursuing profit motive means making everything cost as much as you can get away with, which means locking things down wherever you can, which means slowing society down.
