As someone who has been engaged in children's lives in the age range of 4-9 that have struggled with school, I can't imagine using AI being a net benefit to them. You know what helped me succeed in helping these children more than anything else? Listening to them. That's it. Listening to them to understand their viewpoint and perspective on the world, their interest areas, and the things they were curious about. Then you incorporate those things in how you teach them through direct one on one instruction. It's that simple. My niece, as an example, is now at the top of her class in most subjects and has realized she has a passion for history and geology.
Not every child has the benefit of involved adults in their life, but I'd rather solve that problem than think AI is going to fix this. You're proposing taking one of the most vulnerable populations in the country and manipulating them (intentionally or not) to be reliant on one of the most exploitative technologies that has ever existed. I don't think your intent is evil, but the product here is evil. Remember that the path to hell is paved with good intentions.

There is no clean fix to this problem and there never will be. Attacking anyone who tries to come up w/ a plausible solution is not the answer. And calling everything that you don't like evil is just childish. People deserve to have these tools at their disposal to at least ATTEMPT to improve their children's reading skills.
