I have always felt that kids will get out of education what they put in/their interest in actually learning. I also think there is some benefits to learning how to manage technology de jure as it's likely to come up when they're out of high school too.

I kind of disagree with some of the points about learning more just talking to an AI, both because I tend to get wrong answers or important missed context in my AI testing, but also because I think I needed to learn some stuff I wasn't interested in personally.

Today I don't really have much opportunity to interact with classes beyond the great courses and linked in learning, and unfortunately much of the newer content is more like a YouTube curated Playlist than a traditional course. They are mostly superficial overviews more intended for entertainment than learning details.

YouTube on the other hand is all over the map and you have to know what to search for.

I think some value of the experiment is the part where it got the kids to review their notification settings to suppress things they weren't interested in. Personally I think having phones in airplane mode / off during class is probably the best plan. Do the notifications during study hall, lunch, bus ride, and other free time.
