Google Home (or) Google Spy

In the last years with advancement of technologies we used to hear about new fears like security attacks, privacy breach, and that every smart phone is a potential mic.

In the last Google IO 2016, Google introduced Google Home.

My friends saw it as mimic to Amazon Echo, I saw it as threat.

Google advised to put a unit in every room, even the 'bed rooms'!!

Imagine two married couples are arguing about the last time the husband said 'I love you' to his wife and they ended up by asking Google Home, which answered by date and time.

Now lets imagine something more extreme, the husband asked Google Home what his wife was telling her sister about his mother, or even if he asked Google Home if his ex was better in bed.

Now answer this question honestly, Can you really live naturally knowing that this spy is active under the same roof??
