Is it possible that a jailbreak is found that could allow a “kexec” kind of thing to load a new OS? Of course it would be a huge amount of work even if theoretically possible
marcan once said this was not possible on M1 macs. It was possible before, as coolbooter demonstrated, but it seems now that the hardware cannot be completely reinitialized without being power cycled (it was on Mastodon in 2024, he has since deleted his account so I cannot give you the exact quote). But you can do wizardry to load macOS' userspace on top of iOS' kernel [0] with a jailbreak.
