Three thoughts on AI and education: 1. AI makes plagiarism trivial. It also makes original thought more visible than ever. We chose which one to fear. 2. In a world where any student can consult a thousand experts before lunch, the real exam is not what they know, but which voices they choose to trust and which they choose to resist. 3. When thinking can be outsourced on demand, education is no longer about solving problems. It is about deciding which problems are worth solving.
