I do not use smart devices. Personally, I don't like that they're constantly listening to me, and I don't see the point in them most of the time. Sure they can do some cool things but that's hardly a reason for me to get one. I don't even keep webcams plugged up and I've disabled my microphone on my Android. Even then, I know that I'm not totally free from privacy breaches, which I hate, but in this day and age it's pretty difficult to get completely away from it all.
Also why in the actual hell do people need smart FRIDGES??? It keeps your food cold and you can sometimes get water and ice out of it. What sort of business does a fridge have to be doing literally anything else I just don't get it
