Well, that's the very nature of the employer / employee relationship. In my case I write software for my customers and I trade time for money. If I use an AI to write code two times faster my daily rate doesn't double. However I can keep my costumers.

That's only another step in the path I experienced since the 80s, when I had to type every single character because there was no auto complete, no command line history, very few libraries. I was very good at writing trees, hash tables, linked lists and so was everybody else. Nobody would hire me if I were that slow at writing code today.
