Who in their right mind would bring this kind of intrusive technology into their home, right into their most intimate space? I seriously don't get it. I mean what's wrong with keeping a pen & paper shopping list on your fridge?
Also a lot of people rent studios and one bedrooms or otherwise have open floor plans.
Not to mention I think the paranoia about these home assistant devices is overblown. Do you use a smartphone? In your intimate kitchen?? It has just as much capability to listen to you.
We have a saying that loosely translates to “If the barn burns down, so does the house”. The meaning is that it’s not really wise to let the house burn down if the barn is burning.
