So I've been working with Salesforce for about a year now, as a developer and consultant, and something I've been running into a lot lately is code rot: code that lives tucked away somewhere and never gets updated 'cuz it's working and it was made by someone who's no longer in the picture and nobody knows what it does. Or code that has ceased to be relevant or used for months/years, but no one's stopped to go in and remove it. Or that thing that happens when you have a whole bunch of different people doing work on your SF org, and they're all from different companies and have different standards and levels of skill and so on, and nobody wants to take the responsibility of updating or fixing somebody else's current or old code.
