The most terrifying thing about this episode is that it's pretty much what China's doing with their Sesame Credit thing.

Dominique doesn't have a smart-home - it's an Amazon Echo, which is why she uses the wake-word "Alexa." This is especially important, seeing as how tech-savvy the character is, and how the first episode established that having a smart-home isn't necessarily the best - or most secure - of ideas.
