I think the difference between highly educated and not-so-highly educated is often that the highly educated had coaches. There were people in their lives that corrected them.
I coached my son at soccer. He resists any coaching from me, because I'm his dad. I can tell the same thing to another kid and they will often listen and improve. Those kids keep me going as a coach. My son gets better coaching from his peers just by seeing other kids thwart his attempt to score; that's better coaching than I could ever give anyway.
But, my point is that AI can be a coach to all. AI isn't going to care if you are hurt by it telling you: "Here is how I am breaking your sentence up, and it does not make sense and I'll show you how I interpret that." A tutor might say that in a denigrating way but hopefully a kid won't hear that from the AI in the same way.
AI could be an incredible coach to so many people who wouldn't have parents who could afford it otherwise.
There is still a social component that has to be overcome. If for example a childs parents embrace ignorance that this child out of the gate as a disability. They will have a more difficult time even presented with all the proper tools over a child whos parents embrace learning new things and intellectual exploration.
I hope these tools can help everyone learn, but I do fear the limits will not be them, but it will be us.
It will be interesting if only the highly educated are able to best leverage this, because that would be unfortunate and would accelerate inequality.
I also really hope this can be used to improve learning to bridge this gap, and this summer I will have my high school intern use this technology frequently with the hope that it accelerates his improvement.
