Thanks for the comprehensive answer. I was hoping for something more like an alt-OS for the TV, so it doesn't ask for updates all the time or really do anything besides cast from a computer or console
There was this new technology in the 80s that took over in offices. It became so ubiquitous that people bought the machines to have at home, and it found a less-than-optimal use-case as a general communication device. In the 90s, as its popularity boomed, it would be totally reasonable to make the same assessment you just made, that they would never go away. But when was the last time you used a fax machine?
Unfortunately though, the Internet didn't go away when the dotcom bubble burst, and this is shaping to be the same situation.
