A guided video lesson

Understanding is the new bottleneck — Geoffrey Litt, Notion

As AI agents make code production faster, human understanding becomes the bottleneck for staying in creative and collaborative loops; AI should therefore generate explanations, quizzes, interactive microworlds, and shared spaces that deepen understanding rather than remove people from the work.
