> The fact that he even got that far with emulating what is essentially completely undocumented hardware is a very good sign, adding the rest of the hardware to QEMU might not be as hard as initially thought.

I'm less convinced—it sounds like he was largely reusing the setup that can semi-boot iOS (which is of course also totally undocumented, but has had many years to be studied.)

It's still a cool accomplishment, I just don't think it necessarily portends great things.
