As with all technology, it's about how you use it. I recently made the decision to get some echo devices for our house and I have 5 kids. I thought one of the benefits would be the fact that our little non stop curiosity kiddos who can't yet type or spell every word they want information on, can now ask Alexa questions while my hands are full with dinner and I don't always know the answer. I don't intend on them to learn manners from Alexa, that is my job and kids learn best thru modeled behavior. Also I see this as a way for me to introduce AI to my kids before it's matured to the singularity.
