No joke, I saw a comment in my code base literally yesterday written from a week ago. I said this is crap and it's taking me more than 5seconds to understand and I ended up simply changing some variable names and refactor the function. It took maybe 2 minutes to do but now I don't need a comment and it's cleaner code for future changes. (It's in a file we are actively working on and WILL change)
tl;dr: Refactor not comment
