I said it may be one of the most important Integrated Circuits (ICs) ever made. That’s a bold statement. The 555, 805, or 7400 might all qualify for such a distinction. My feeling about the 7805’s importance is because it is a chip that is still popular today. It is used, or at least was used, in so many applications. And it is the heart of many 5V digital systems.
