I don't know why there was ever an expectation that teens would know more. People that are interested in a topic know more, its not a factor of age. The same could be said of cars, boats, household appliances, anything! If you are interested you will learn and if your not you won't. Exposure and use on a daily basis does not imply that you will know whats going on under the hood, a literal old car metaphor for understanding whats going on out of sight. The majority of people drive or are driven in cars and only have a cursory knowledge of how they work and the thing is they don't need to and that's how it should be. We don't expect people to understand in detail how their cars/trains/elevators/coffee machine/hair dryer work, why should a computer be different?
