I'm sure all the time; all people and processes are fallible.
But that's also why documentation is so important in this space.
I spent 15+ years building software for pharmas that was subject to GxP validation so I know the effort it takes to "do it right", but also that it's never infallible. The main point of validation is to capture the evidence that you followed the process and not that the process is infallible.
As long as that validation process is still as rigorous, I don't see much difference.
