What you're describing is a fad that has subsided a bit over the last few years. Cambridge MA stopped teaching 8th grade algebra because they didn't like the racial disparity between students in advanced vs non-advanced math. There was a significant backlash from parents, and now they're bringing back 8th grade algebra. The debate now seems to be much more about how to offer more advanced math than whether to offer it at all. A similar dynamic seems to be playing out in other towns as well.

A positive change for sure but what about the kids who were stunted developmentally during that time?

In a nearby elementary school they are now touting teaching kids “AI literacy”. At an age where they don’t even have enough of a world view to understand anything related to it. Such an asinine idea, and of course it will be at the expense of something non-trendy.

It seems like public education suffers from so much “idea cascade” now and jumps from one fad to the next. Educational paths are more and more left to chance than organized thought.
