I guess it could go wrong and turn my kid into a monster, but how can you win if you don't play?
Having kids is an iterative process anyway, just keep making them and it will work out :)
I don't know when that will be, but if there's one thing I do know it's probably not until double digit age or early teen years.
I have no intention of giving my kids free-reign of infinite feeds of content. They can however do whatever they want in their time allowed on the internet, but it will be reviewed occasionally to make sure it's not going down a bad path like some of the horror stories I've heard from other parents.
Either you teach them, or the world does.
Probably will loosen up some by middle school...maybe age 12ish?
The thought still terrifies me, though.
Way more interesting question is how to get a decent censoreship to the kid at the age X. F.e. I would not introduce kid to Tor before maybe 7 yo.
