does alexa dream of electric sheep?

I heard a strange story today about Amazon's new talking home avatar butler called Alexa. 

A kid ordered a doll and some cookies via Alexa, who [which?] has the ability to order stuff online [a bewildering thought in itself] and the story hit the TV news.

Whilst on the news the kid's voice must have been repeated telling Alexa to order a doll and some cookies. 

Now the unbelievable bit. Many other Alexas in other homes heard this and went on to order dolls and cookies too! 

I don't know if this is true [please don't let it be fake news] but it reminds me of the trope of IT going sentient in so many sci-fi stories and films. Just think of Cyberdine Systems in Terminator - and we all know where that lead! - 

and what about the classic ending of Lawnmower Man, where the digitised Jobe goes sentient and makes all the world's landlines ring at once.

I suppose I can't ignore Wargames either where WHOPPER orders nuclear strikes everywhere. Maybe WHOPPER started by ordering dolls and cookies! 

Does anyone have an Amazon Alexa unit [which maybe called Echo] ?
