> We are supposed to parent. Part of the parenting stuff means supervising and guiding in all environments your kid has contact with, including screens.

That's your interpretation of the parenting role. It might be agreeable for a lot of people on this forum, but that's mostly because we're all a self selected group.

Historically speaking, children were free to learn unguided and parents only interfered if the kids didn't do their jobs, which was literal work on a farm or similar.

I'm not advocating for child labor, but your opinion that it's your job to literally supervise your child learning is also a quiet extreme position from my point of view.
