AI is not just about increasing personal productivity by finding answers and helping with writing. It can also be a powerful stimulant to real learning as a cognitive antagonist. A cognitive antagonist is a person or a system which questions assumptions, arguments, and/or conclusions with the purpose of increasing the insights of those concerned. This process is critical and challenging, with the objective of deepening understanding. This is another way of thinking about the classical dialectic, which describes the same cognitive friction and is central to learning.
