My only concern is that we have to come up with a plan that can be explained to the 100,000 or primary school teachers in the USA. Rarefied curriculums are like rarefied programming languages -- they don't "take", or they just distract. We need a Python, not an ML to explain to folks, and, honestly, "drill the crap out of your students and test them regularly" is easy to explain in a staff meeting... and would be a vast improvement over the BS that passes for education these days.
