So, let’s do this again, but this time cleanly. In a Facebook Post, Michael Seemann has been explaining why the Facebook App does not listen to every word you ever say, all of the time.
He is right. A telephone is a device with limited power supply, limited cooling and limited, metered connectivity. It has an operating system that monitors and manages these critical resources, hard. You can’t listen to things all of the time and expect not to be noticed. Like, “the battery is empty and my LTE budget is gone” noticed.
Other devices, an Alexa, a Sonos One or a Google Home, are on cabled power and unmetered Wifi. The could theoretically get away with listening all of the time.
So how much data is that? Let’s do the math.
