# Quote of the Week

<!-- QOTW goes here -->
> `/proc/self/mem` is outside the scope of rust's safety guarantees. otherwise this would open a can of worms that could not be closed except by forbidding debuggers from poking memory or marking every impure function as unsafe.
>
> like, what if you invoke gdb to poke memory? what if you modify .bash_profile to poke memory? what if you send an http request to a hypervisor to poke memory? what if you run a spin loop, and the noise of the fans whirring up activates a beam of ionizing radiation pointed directly at the CPU? what if opening the disk drive makes the computer fall off a cliff?
