Self-interest guides opposition to change, but lack of self-awareness fuels it even more.
Once you master any system, you typically become blind to its flaws; even if you can see them, they appear far too complex and intertwined to consider changing. But to remain blind is to risk becoming the music industry, in which self-interest (trying to protect short-term gains) trumped self-awareness (few people realized that the old system was about to be overtaken altogether). Industry executives clung to their outdated business model - selling albums - until it was too late and file sharing and iTunes had turned everything upside down.
