Feels like there’s a pretty big arb for publishing children’s books right now. 

Claude for writing / rhyming
ChatGPT / Midjourney for images

Maybe the bigger opportunity is animating and then making Peppa Pig / Bluey competitors on YouTube.

Publishers need writers anyway or it'll just be AI slop books people don't want. Most writers don't need it, they can just write the children's book normally and it'll be much more meaningful. It's nice to expand accessibility options for people who do need it though.
Animation yeah but I'm not sure the tools are there for people yet really. Clips people are sharing are ok but not coherent as long form content. To make it into a really good show that will catch on, I think it takes a huge amount of time and resources still.
