Money is simply a universal equivalent of that value, nothing more. So if you give me a breakfast for help with unloading your truck, it's still an exchange, and my work's value is equal to "one breakfast" even no money was involved.
AI is just a nail gun, there still needs to be somebody who trains/operates it (like with ChatGPT) and who will ask for something in exchange. It may eliminate some jobs (happened before), but it will create others because human society is not only about food (not sure ChatGPT can help here though), but about interactions which are not going to be automated by ChatGPT (think of sex, power).
