I have an Alexa in my bathroom. It is convenient to use to listen to music and check the weather while I get ready. If someone at Amazon (or the NSA) wants to listen in on the things that happen in my bathroom, go right ahead. Very little of my life happens within listening of my bathroom.
More importantly, I carry a mobile device with listening capabilities and internet connection in my pocket basically at all times. I can turn off Siri or Hey Google but again I have to trust that it really is off. I have to trust that apps like FB or Twitter aren't recording while I use their apps. Additionally, I can't stop all the people around me from having Siri or Hey Google turned on. This doesn't even cover the ability for a 0-day to be exploitable on all handsets and used by a state level actor.
I unfortunately think the ship has sailed on complete privacy in today's online world. Everyone is being tracked, today to sell ads but a dystopian future is largely inevitable. Our mobile phones are tracked but also our digital payments and our cars as we go through tolls (or completely if you have on-star or wi-fi cars) and our movements as we use ride-share and even our walking as traffic cameras are extended with facial recognition. The only way out is to be completely off grid in a self-sustaining farm.
