same in programming... unsafePerformIO, dropping into native code or assembly, etc. In 2013 the hardware exposes a mutable interface.

I think that's fundamentally different. Breaking immutability in a language by stepping outside the language is still programmatic. Breaking it via administration is a human decision.

In programming, it's a conscious decision to break immutability (assuming a language that supports it). It administration, it's a conscious decision to enforce it.

And it's really bad practice (at least in Haskell) to truly break immutability. Uses of unsafePerformIO are strongly urged to be "observationally immutable, pure, safe, transparent".
