They probably had internet in Atlantis, or something like it, so that would be a shutdown of like 20,000 years or so before it was invented again.

Disconnect your TV from the internet and don’t let it update (downgrade) your software.

Specifically 18.4 to 18.7. I’m still on 18.1, so presumably not vulnerable to DarkSword. And Coruna is iOS 13 to 17.2.1. So even on 18.1 there’s no jailbreak on the immediate horizon.

Apple has longer support for updates than any other manufacturer. This exploit is for iOS 18 and it was already patched for most users on most devices by the time we are hearing about it.
