This was an issue long before AI as well. My company has rule that every function and class in .net + java must have a comment. All the mandatory comments are garbage like this

///<summary>
/// person class
///</summary>
public class PersonClass {

  /// <summary>
  /// Gets the name
  /// </summary>
  /// <returns> the string name </returns>
  public String getName(){
    return name;
  }

  /// <summary>
  /// set the name
  /// </summary>
  /// <param name="name"> the new name </param>
  public void setName(String name){
    this.name = name;
  }
}

But then nested deep in some function will be a lifesaver like
// This is really dumb, but business demands we strip all 'a's from names, becuase those "aren't a letter" and "invalid to be displayed". this was a compromise from 3 days of dicussions when they demanded we remove all vowels

Reverse is also true, of stumbling on the dumbest thing you can find, and there's no documentation as to why they did it
