@mike Good post. Smart-home, smart-phone, smart-watch, smart-speaker etc seem mostly about data gathering. The focus clearly shifted from building actual useful products, to data gathering devices where the usefulness is just there to ensure people use it enough so it can get more data. And most of the product design these days isn't what is good for the user, its just based on what the previously gathered data told developers is most addictive/viral/attention-sapping.
