Looks to be back now.
So if you've got a ticket, there almost certainly was a sweeper that came by at that time.
Overall it's been a successful approach, and I recommend it to new learners unless they have a particular interest in being able to write by hand or they feel strongly that writing the characters helps them remember them.
It's only rarely that I have to write anything other than my own name in Japanese. I've practiced my address but writing it in English is fine in 99% of situations. Being able to write properly would save a little embarrassment, but I still believe my language learning time would have a much higher ROI in other areas.
This feels like the LLM-enabled version of this behavior (except that in the former case, students will quickly realize that what they’re doing is pointless and ask a peer or teacher for help; whereas maybe the LLM is a little too good at hijacking that and making its user feel like things are still on track).
The most important thing to teach is how to build an internal model of what is happening, identify which assumptions in your model are most likely to be faulty/improperly captured by the model, what experiments to carry out to test those assumptions…
In essence, what we call an “engineering mindset” and what good education should strive to teach.
