In the future, won't it become increasingly difficult to keep your TV disconnected? Anything you connect to it will provide it with an internet connection.
Don't see any evidence of that actually happening as of yet. Would more expect that they'll just make them stop working entirely without a connection, instead of adding fancier ways of connecting them.
Maybe we'll have "HDMI condoms" that connect two cables and drop all packets relating to internet sharing.
They could create an HDMI condom so you can't have network connectivity over HDMI. Similar to USB condoms.
Also... what if they put a 5G SIM card inside the telly? Now that would suck.
That does seem inevitable. Time to build a faraday cage for our TV's.
