It literally helps future programmers. There is nothing more inspiring than reading comments you can feel solidarity with. These literally are load bearing comments.

I also enjoy the sarcastic "I won't regret taking this shortcut" comments. Like, you're trying to fix some ass-holes code and they are literally mocking you for the fact that they knew they did it wrong but it would be someone else's problem in the future. It's a "pass the torch" kind of thing that I always enjoy. Like, I can't be mad because I just feel so connected in our mutual frustration of wage labor bull shit.

The day I cannot swear in my code is the day I auto obsfuscate the whole thing so I can continue using swearwords but now also nobody else can work the code
