It's kinda tragic too. I do agree with the sentiment behind age verification, it is in the kids' best interest that they not be using porn at that age. But there's really no way to effectively enforce this without violating basic rights. There is no good solution. Given that dilemma, all we can do is try to better prepare parents to deal with this in their home.
Probably just down to less stuff running in the background using up CPU cycles. I can't imagine it makes a huge difference, but more than nothing.
