Parents still have the ability to raise their children according to their own values, despite the most earnest and eager intentions of the dopamine-dealing crowd. That bug hasn't yet been engineered out of society.
Yet when we do this by, say, homeschooling, the HN commentariat piles up hundreds of comments accusing us of child neglect and a lack of concern for society.
You are right, parents can still steer their children.
But in some cases like mine, parents might not have the time or inclination to do so, for whatever reasons.
I was able to discover Pickwick Papers, Hardy Boys, Harry Potter, Lord of the Flies, Spirited Away, Almost Famous, etc. on my own. If I were young today, I don't think I would discover the right things.
