I don't think reading and maths needs to be obligatory. Kids will pick it up naturally through their own curiosity when trying to learn about something more advanced.
What you are describing is pretty close to a university. Which makes sense because universities are places of learning, unlike schools which are prisons of disciplining and the goal isn't to learn but to memorize minutia for about a month before moving to the next topic.
knowledge will obviously come from other sources too. When kids socialize with others they will learn things naturally, and discussion should absolutely be encouraged. However AI produces a lot of problems. AIs have bias based on the information they learn, they require resources to build and maintain and cannot discuss information accurately. I just don't see what AI adds over just interacting with other people.
Solarpunk societies, like all post-capitalist societies, are build on strong human relations, replacing one of the avenues of creating them with an hallucinating rock (exaggeration I know) just seems weird.
