It's probably true that asteroid mining will never be economically viable for supplying Earthbound industrial processes. Where it might possibly be useful someday is if we ever try to do manufacturing and industrial processes in space. Absent completely sci-fi propulsion technology, it will probably never be a good idea to launch bulk raw materials out of Earth's gravity well.
