I agree -- all ATMs, voting machines, slot machines, electricity meters, traffic lights, navigation systems, safety interlocks, etc should be hackable. I'm sure that no idiot teenager is going to change the firmware and allow an unsuspecting person to use the device.
Aren't they? Just break the seal and use a screw driver and some other tools. And when it comes to some voting machines you don't even need this.
You don't understand at all what we are talking about, or what security means and how gets implemented, or what certification procedures are about. There is no difference between conventional (even softwre-free electro-mechanical devices) and software. There is just a lot of clueless people.
