I do as well.

I also think that to some extent, there's a failure of the system if it presents to the student the idea that this is a viable strategy for jumping through the hoop of a test. We don't give tests in ways that truly test understanding; we tend to give tests in ways that prove the ability to retain and regurgitate information, and in many cases we set up situations where it's not stupidity or laziness, but rather necessity: "I'm working two jobs, my kids are hungry, and I'm expected to spend two hours sitting here regurgitating information -- I have to find a strategy to get this done faster. I know I know the information, I just don't have time to perform it for the teacher."
I know that's a realistic situation, because I've lived it. Except I didn't have ChatGPT, and instead my work and my parental skills suffered for it.
I do think the student learned a lesson from it. I also hope that our pedagogical system learns a lesson from the whole "threat" of GPT as well.
