Alexa is the least of our problems, we are literally being recorded everyday, probably 10-20 times a day.
The minute one walks outside, there are satellites taking images, everywhere you go has a camera, street lights, stores, malls, every business you visit has a camera, so whether your driving, walking or patronizing a business, your being recorded.
And last but not least, every cell phone is easily used to listen to your conversation and locate you without you even having it on, and let’s not forget computers that hackers can easily get into and out without you ever knowing.... Alexa is just another technology to listen in the home, but if you have a security, they are listening through that, bottom line... you cannot get away from it unless you hide in a cave and have no WiFi or electronic devices that connect to the internet.
