It's effortless (nearly 1-shot prompt) to take essays and long-form text (e.g., PDF textbooks) and turn them into interactive, visual apps. Add in spaced repetition, exercises, quizzes, and gamification as you wish. I like to call this book juicing-- getting the sweetest parts of a book or text.

Every author could do this for everything long-form, as the cost is so low. Or do this for yourself to learn in an engaging way, along with the original text.

From the original essay, "The Adolescence of Technology" by Dario Amodei, CEO of Anthropic.
