Is this still "society's" concept of adulthood? Or is it just certain demographics? Most people I know in tech-type careers still play video games (or would if they had time), read a wide range of fantasy and sci-fi books, enjoy hobbies etc. I would regard someone as being immature if they thought that, as an adult, you shouldn't do the things you enjoy once you've met your responsibilities.
