On top of the pretty bad article, HN finds the “can’t win” scenario again. There’s no age verification scheme that will survive “collusion”, that’s when the adult allows the minor to use validated credentials, devices, etc. And whatever more intrusive age verification schemes we come up with will also fail this but add the intrusiveness to ruffle even more HN feathers. We can have the constant face, fingerprint and DNA scan for as long as the sensitive apps is used. Everything gets stored on a central server for safety so your kid can’t hack the device and replace the reference sample. /s

Love the magic step in the middle, unlock my app. Ask for passcode or faceid to “unlock your app”. That’s a lot of legwork the adult has to do so the child can “trick” the system.

Some people will forever be shocked that if they leave on the table an open booze or medicine bottle, loaded gun, etc. a child can just take them and misuse them. The blame is unmistakably with bottle and gun manufacturers, right?

Put a modicum of effort to protect the sensitive apps or supervise the child when you share your device. They can do a lot of damage even with age appropriate apps. Wanna see how quickly your kid will tell everyone on the net how much money you have (via proxies), where you live, and when you go on vacation? Or tell someone the credit card number they swiped from your pocket if the other person makes it sound like a game?
