It all started with a seemingly innocent Google blog post earlier this month, in which Google announced that their ‘Hey Google’ Google Assistant was ready to go live on Nest Secure Nest Guard home security devices. Then people started having that ‘waaaait a minute…’ moment: this meant that there had to be a microphone in that Nest Guard device.

Google has just announced that it will acquire Nest Labs, the company that has put smart thermostats in homes. Meaning that Google will now be monitoring your home for you.
