Basing your security on Movie plot threats is a pretty bad idea.
E: also somewhere in the NSA there is a junior analyst feverishly writing a report right now:
We should stop developing AI, we should collect and destroy the hardware and we should destroy the chip fab supply chain that allows humans to experiment with AI at the exaflop scale. Since that supply chain is only in two major countries (US and China), this isn't necessarily impossible to coordinate
(somebody on LW highlighted the last line as important (I also think the line is wrong but im not going to 'somebody is wrong on the internet' help the wannabe terrorist cultists)).
