For example, we have standardized schooling/exams, because that's the proven scalable way we can have for children - essentially a factory spitting out different grade levels/seniority.
But LLMs can break this standardization by being able to tailor student needs in a scalable manner.
However this takes a huge amount of action, and that's going to be the pain point in the near future as we humans tend towards the easy/greedy paths.
Cultural richness - LLMs are also very bad in this regard due to the bias towards majority viewpoints. This reminds me of a recent HN thread [0] discussing how AI is hindering the adoption of new technologies. In some ways, this happens because AI tends to favor mainstream perspectives, making it biased against "new" or "fringe" viewpoints.
