"In the context of child education, it doesn't matter at all if it will "materially shape how people work in 10 years"." is fundamentally wrong.

It absolutely matters. That's the entire justification for why society spends what it does on education: to enable individuals to contribute to society when they grow up.

K-12 education is not supposed to be a liberal arts education in the classics. It's already drifted too far away from imparting useful life and employment skills.
