Russia China and every hacker w a keyboard has been doing things like it seems non stop as per publicly reported stories -

its obviously an important national security interest so I'd think the govt would be seeking out every available tech to solve that problem

PC tech is my nemesis and yet i've been aware of the problem for many years and have often thought PC's/mobile devices are NOT ready for prime time when not even the govt's goon squads can keep PC's/mobile devices safe

it would be like building a car w no brakes whose operating systems could be overtaken without notice
