@njamster I do not think it will pick up in any major ways. Making the actual tutorials/walkthroughs is a lot more time-consuming than making articles and videos.
With our app Learn GDScript we had made an editor (not the best but usable for a test before doing more UX work), and we talked to interested teachers, but nobody ever designed lessons or exercises with it. Teachers just use what we produce in their classrooms instead.
You could argue it's the editor UX causing that, but as we're talking fellow professionals who care very much about their students, and whom we directly supported, I don't think that was the problem.
I think it has more to do with the sheer amount of time it takes to design, test, and iterate over interactive material. It takes lots of QA testing.
