What happens when you screw up?
Non-engineers want to know: what happens when a big bug is found in your software, and the bug is causing real users real problems, and you’re the one who wrote the code?

But shipping production software involves a lot more than writing code. It goes beyond that one engineer. That engineer is not the only person who saw or ran that code.
