As a parent who's was "Why"ed to death by two curious kids in the pre-google era, I can tell you that I would have killed for "someone" to take on a part of that burden! ;)

>>I couldn't help but think it won't be too long until kids don't need parents much

I think you meant need as pure "question answerers," but we do a few things for the kids that Siri and Alexa wouldn't have the stomach or, for that matter, the arms for. Oh, also: love!
