"Unhackable" is such a vague, nebulous, weasel wordy term, I'm surprised I don't need a nebuliser to inhale it. So much of this shit sounds like Comp Sci III that I don't know where to begin. And I'm sure, neither do they.
Unhackable from what perspective? Software, hardware, internet, certain protocols, are the important bits armoured in gold like SIM cards, what? I really don't get it.
Nothing is unhackable. Nothing can 100% perfectly stand up to human curiosity, insight, and intellect. We live in an imperfect universe, and we are imperfect beings. How can an imperfect being make a perfect anything? It might take a few more significant digits to find imperfections, but they're still going to be there.
P.S. oh my god, that music is so goddamn grating on my nerves, that I'm going to go carve "me has smart braneing" into my marble countertop with my teeth to make me feel better.
