Hello David. You speak exactly what's been on my mind for a very long time.
I also occasionally teach drawing young students, and I always see them express so many interesting thoughts and ideas that I otherwise would never seen coming from them. Yet, drawing has become such a lost art in the big sense. I applaud you that you keep it in your curriculum,
No one, no matter what age, should be afraid to hold a pencil in their hand and draw a line on a piece of paper. That line will become two, then three, and so on, and eventually a story will emerge that we'd not been able to express in any other way.
I think that AI and creative thinking are two very different categories.
