My goal is for them to learn. And yes, I can just carry on, and some will cheat. I've caught cheaters in the past, of course, but they were far and few between. With ChatGPT and even improved translators like DeepL, it's hard to get them to do the practice they need to learn.
And as a teacher who really WANTS them to learn and to get that feeling, "Hey, I can actually do this!", it's depressing to think of the one who do cheat themselves. Oh well...
