What is AI fluency?
AI fluency is the point where using AI in your work stops being an effort and becomes second nature. You know when to reach for it, how to steer it, and how to judge what it gives back. It is a practised skill, not a fact you learn once.
Fluency in anything comes from reps, not readings. You get fluent in a language by speaking it daily, and fluent in AI by using it on real tasks until the moves are automatic.
That is why fluency fades without practice and why it has to be rebuilt as the tools change. A system that gives you a daily rep on your own work is how fluency is built and kept.
Literacy is understanding what AI is and its limits. Fluency is doing, using AI well in real work without thinking about it. Literacy is the floor, fluency is the goal.
