Such absolutes are always an indication that you should be extraordinarily skeptical of this person's advice.
Life requires you to adapt with current technology, and be flexible in the paths that you choose to follow your dreams. People who obsess about following paths when there is nothing to be gained by insisting on the absolute, are always to be suspected. (Warning: You may have a died-in-the-wool bureaucrat on your hands)
Your goal is to be successful in reaching your dream. Your goal is not to focus on the minutiae in life. Who cares if you have some paper documents and some electronic documents in your office? Flexibility is required to be successful. Steadfastly fighting for absoluteness on irrelevant topics is dysfunctional - always.
