What are the benefits of writing-?

Writing is communication. That in a nutshell is the benefit of writing. Nothing can be shared without communication. No letters, no memos, no cave paintings, no newspapers, no Television, no radio, no Video Games, no business, no entertainment, no books or magazines, no school, no education, no knowledge passed from one person to the next, one generation to the next, one civilation to the next. No history.
