I hear this "oh but we're so smart, remember how many regular people there are!" thing often on HN. I'm reasonably sure the person you are imagining is not average, they are sometimes called the lowest common denominator. Even my old highschool friend who delivers pizzas hates smart TVs and can tell good UX from bad. My other one, and his wife, both non-technical computer haters in non-tech fields, have covered this topic and said they miss when things weren't so "smart", and would rather be in charge of buying a playstation/Roku/whatever to control their TV.

Big businesses chronically underestimate consumers, don't try to teach them anything, and don't give them options for fear of confusing them. They forget everyone who works for them and their partners or makes the things they consume are also the consumers they abuse.
