This is marked funny, but think about it for a minute. Our computers, phones, tablets -- even watches -- are collecting way more information than this Barbie is and yet how many people think these ubiquitous machines are creepy? Not many. The lesson here might be this: the shape of the surveillance device doesn't make it creepy -- what it collects is what makes it creepy. Oddly though, very few people are creeped out by their own phone.
Two conclusions based on "shape irrelevant":
1) Barbie, phones, computers etc. etc. have become extremely creepy surveillance devices (this is where I am, which is depressing, because I've loved technology for so long).
2) Barbie, phones, computers etc. etc. are surveillance devices and surveillance is totally not creepy -- just don't care.
To mix and match 1 & 2 though, making barbie creepy and siri not, is inconsistent and illogical.
a good childhood is about innocence, fun, and the world being in general a good place.
Big Brother is there to help with that.
