Everyone knows the real comments and documentation are stashed and hidden in git commit comments. I'm kidding, but many companies rely on this information in the ticket system.
Depending on the language, Inline code comments can be a security risk. I have used comments in Java and C# to help design an exploit for the software.
Edit: ctrl+f todo (find all the gaps lol.)
Also, isn't AI now the solution for just-in-time code documentation?
