He seems to believe that the only reason for a comment is to describe what something does, and thus clearly-written code would be equivalent. If that were strictly true, he may be right. However, a major benefit of comments is to explain why something is done a certain way. Is anything temporary or arbitrary? Is there something counting on a side effect? Is something being bypassed for efficiency? How will this null argument to a function be interpreted? Is something not being checked because it is assumed to have been validated earlier? And so forth.
