Do you have one of the "smart" speakers in your house?  The ones that you can ask questions of, and make your life "easier".  

I don't.  I don't want one.  I don't have one. And although I say, never say never, I have no plans to ever have those in my house.

Perhaps I am paranoid, but I don't like my personal space being invaded.  I am not afraid of computer technology, video phones, and the like, but I want them to only be listening (i.e. recording) or watching (i.e. video recording or transmitting images), when I say it's ok.  That's one of the reasons I WhiteCoat Risk Management has video shutters available for our computer cameras.  No software can bypass a piece of plastic over the lens of the camera.  

Back to Alexa.

Yes, those smart speakers creep me out.  I don't like the idea of being "listened to" all the time.  And these are everywhere.   So you need to be diligent in shutting off those...
