Do you... change your tires? Or just get a brand new car every year to avoid the hassle of dealing with car shops?
Problem with Smart TVs is they become obsolete super fast software wise. And basically, unsafe to connect to the internet in a few years.
Most TVs have CI+ ports. I can easily imagine an upgradable "smart module". Just buy a new compatible one (which, effectively could just connect for power and HDMI) and get the brand new stuff.
There is no bubble, smart TVs are a consumerist trap and it will require government intervention to fix because nobody has any incentives otherwise.
