This does not make sense. You can create a very complex system out of
screwdrivers and still each screwdriver would require no update.
Systems consist of computers and computers of software modules. There is
nothing inherently complex about making a module safe and bug free.
Security interactions are primitive and 100% functional. There is no
difficult issues with non-functional stuff like real-time problems. It
is purely algorithmic while all mathematical complexity of cryptography
is NOT what gets updated. It is complex only because it was designed as
a Wood Block Tumbling Game.

I don't need a bank account to fasten the screws. Application area is
irrelevant.
