In my experience, it is not generally a matter of putting some quick and dirty script in the solve a problem and it goes on solving the problem without modification indefinitely. It is more often:
1. Put a quick and dirty script in to quickly solve some immediate problem
2. When that quick and dirty script stops working, instead of putting a proper solution in place you either add another quick and dirty script in to plug the issue or you modify the original quick and dirty script in some ad-hoc way
3. Repeat over and over again
And then you end up with some impossibly complex Rube Goldberg machine.
