No. Parenting is not about relying on devices.
Parenting is about talking with your children, about discussing things, helping them understand and make informed decisions.
A device is no better than a government filter - it takes the job away from the parents, explains nothing to the children and makes everyone think everything is fine.
Pornography is an important subject, it should be addressed in an adult manner and not avoided at all times
Of course, the discussion must be at the level of the child. I'm not saying that you should tell everything to a 5-year-old, but I am saying that you don't let a 5-year-old loose on a screen without supervision.
