It works well to commercialize existing knowledge, or take some existing knowledge that is 80% complete and then do the other 20%. Business is good as capturing value, not at creating it. In terms of technology it's much the same, the people who created the knowledge often did not benefit from it... someone else did. The ones who did benefit were scientists first in usually a university environment who then sought to commercialize their inventions and formed corporations to do that. Businesses often do not discover these things they commercialized, and maybe it's right to say that some things may not have been as profitable if not for business. And maybe some things would not have been properly commercialized.
