I mean... yes, but also no. C is actually a great example. So much of the code we wrote is about manipulating the specifics of that specific computer system we happen to be using at that exact moment. Everything from cpu specific instructions to how the ram behaves or how much of it there is all the way up to how library functions operate at any given point in time.

And in relatively short amounts of time, it can all change out from underneath you.
