This is riddled with fearmongering. You don't need to be a cybersecurity expert to take interest in your own child. It doesn't take a PhD to enable parental controls or tell your child "no" if they want something that is inappropriate for them.

You might as well have said that you need to be a police officer to make sure your child isn't hit by a drunk driver, kidnapped by creeps or attacked by someone on the street. Children are under the care of parents or guardians for a reason. It's not to fist fight criminals or design their own security system.
