I am afflicted with this disease:

In large measure the high casualty rate of knowledge-based industry is the fault of the knowledge-based, and especially the high-tech, entrepreneurs themselves. They tend to be contemptuous of anything that is not “advanced knowledge”, and particularly of anyone who is not a specialist in their own area. They tend to be infatuated by their own technology, often believing that “quality” means what is technically sophisticated rather than what gives value to the user.
