I'm close to satisfied with the article text.
I'm still experimenting with the best ways to generate the images. I'm very happy with some of them, but unhappy with others. I need to figure out how to create an effective review loop. As you say, I'm not familiar enough with all of the subjects. Like I can't tell whether a diagram of a hearts has all the tubes in the right place.
I think AI is ideally suited to something like this, and I should soon be able to get to a point where I can generate an article, without human review, an article that's as good as that in a median kids' print magazine.
If I reach that point, the next goal would be to match or exceed the quality of the median article in Oyla (https://oyla.us/) or Aquila (https://aquila.co.uk/).
