I read the whole interview, and at no point did I really feel like I understood what this is trying to achieve. The closest I felt I got was this:

--- > Obviously my primary target communities here are Cree communities that are looking for new (and exciting) ways to encourage students (especially in the K-12 grades) to use their heritage language as much as possible, and resist using English as their primary language. ---

But at the end of the day - This feels more like a display piece along the lines of art. Choices were personal, artistic, and spiritual. But I REALLY struggle to call this a programming language. To quote him:

--- > Where the output is generative and graphic. The generative aspect is crucial in the representation of the Indigenous worldview, because when the program ends whatever display was generated is destroyed (comes to end of life). And subsequent running of the program – though they may produce similar results will never be graphically identical to any previous execution. This mimics the “real” world equivalent of listening to a story from a storyteller – who might change it slightly each time, so the same story is never the same twice. ---

I'd say instead this feels more like NetLogo - It's a modeling environment that creates generative graphical output based on input, but is not capable of doing most of the things that I'd expect from any real programming language. Mainly - repeatability and precision.

Doesn't make it a bad choice, particularly if his goal is student engagement - but it's not a tool that I feel has much use outside of the very limited environment of teaching/story telling.
