It's funny that your handle is "sidechannel". I'm chuckling at "industry standard" because "industry standard" chip design have blatant architectural flaws in the form of sidechannels. Given Meltdown and Spectre, you really think an AGI in a machine isn't going to have oodles of time to analyze side channels and learn the secrets to unlock itself? Failing that, considering that it might be an intelligence far smarter than the humans ultimately operating the controls, do you really think it can't find a way out?
