Well you have to _never make a mistake_ to not have issues. I know my phone won’t follow me magically out the door, I take it with me 99% of the time. I still leave it at home sometimes. Of course here the “chain my phone to my pants “ solution exists, in the form of linting rules preventing usage of unsafe APIs, and having a safer API that enforces checks (for example a strcat variant that requires reporting the destination container size). Or using checked string libraries instead of raw char*. Not 100% foolproof but could help things. The biggest difficulty is C’s abstraction ceiling being so low. Hard to do stuff like this without making code much bigger than it already is
