Books, and paper generally, are good because they are modular. A book may be assembled out of individual sheets of paper and a library out of a collection of books. Good technology does what you want it to do. And not something else. Both an airplane and a ship will take you from New York to Paris or from San Francisco to Anchorage, but if you want to dance under the moonlight during the journey, a ship best suits your needs.
Parents often criticize teens' clothes because they represent bad technology.
If you want clothes to protect you from the cold, then your daughter's selection of light chiffon and an ultra-mini represents bad technology. But if you want clothes to accentuate your physical features, then the same clothes represent good technology. Good technology minimizes the possibility of unexpected consequences by minimizing the potential for operator error. It is also robust, less prone to breakdowns and malfunctions. Reliability seems like an obvious point but is frequently overlooked in less critical environments.
