All of those issues are covered by other devices that most people will already have. An XBox360/PS3 or any newer gaming system can output 4k and make the smart features in the TV unnecessary. The same is true of a cable box, Roku plugin, fire stick, or any other streaming device. All the TV really needs is to display the 4k signal it receives. TVs don't even really need receivers anymore just a USB hub, a processor for video and audio output, and a screen.
