truly upon us, there's no human way to keep track of these

Hate to break it to you, but you are behind the times. Compilers
are passe' -- "modern" systems use interpreters like JIT Java.

How else you you think Android gets Apps to run on the dogs-breakfast
of ARM processors out there? It is [nearly] all interpreted Java.
So much so that Dell can get 'roid Apps to run on its x86 tablet!
(AFAIK, iOS still runs compiled Apps prob'cuz Apple _hatez_ Oracle)
