It is one thing to not use AI because you enjoy the process, or because you believe that art is inseparable from the act of creation.

But she claims that the fact that AI exists decreases her drive to create. That is a much stronger and less obvious argument, and something that doesn't apply to you if you're still building those models.

If she simply "enjoys the effort", as you claim, she would do the same as you - continue enjoying it. But she is not.
