The only embarrassed entity here is George Hotz. I find it extremely hard to come up with a charitable narrative in all this but at least the system appears to be working: hacked together crap is not going to be sold to consumers.

It's one thing to break other systems, it is an entirely different thing to produce safety critical software systems interacting in real time with hardware under real world conditions and it is not a given that someone who is good at the one will also be good at the other.
