Why scared? There is nothing to stop someone from hacking a device - but then do we want all devices to be hacked? If Siri is somehow integrated into my car in the future, do I want my kid hacking into it and messing around with it, potentially resulting in who knows what.

The ability to play around and change things is always gonna be there and in fact with locked devices in some ways it's even better - you'll have to be more enthusiastic and perhaps more talented to hack it, and that breeds and entirely new generation of hackers.

And remember - even Apple ended up hiring the person who created his own version of an iPhone notification system on his jailbroken phone.
