I think ultimately it just comes down to the ability to ask a question. Googling did a lot for this, but LLM agents are on a whole other level. When someone can just endlessly ask questions and have them answered directly and comprehensibly, they can get past that initial stage of confusion in learning much quicker. It used to be you needed a human tutor to do this. But now an AI system can track and manage your knowledge graph and slowly level you up through direct natural language interaction.
