I think there's a need to distinguish between childhood education and adult education, in that a main role of childhood education is to facilitate socialization, it's not just reading writing and arithmetic. This is why small class sizes are much more important in K-12 education than at the college level (although college discussion groups led by a TA can be very helpful). Also, personalized learning lacks some of the motizational pressure that attending a class with other people at a specified time imposes. Some people are self-disciplined and get by without this, but having a schedule helps a lot of people stay focused on their goals. Where personalized (nowadays, LLMs) tools are incredibly helpful is if you take a course that's a bit above your level and for which you lack some of the necessary background. With LLM assistance, you might have to work twice as hard as other students in the course to keep up, but you at least won't be totally lost. However, the old saw about leading a horse to water still applies. All the technology and assistance in the world won't help the unmotivated student learn much. If the broader culture doesn't value education, that's the first obstacle to overcome.
