Because despite pointing out exactly why I thought it was true and explaining Obj-C&#x27;s various dispatch optimization tricks and how they still left an optimizing compiler&#x2F;runtime with a far greater challenge, the response was generally, &quot;you have no idea what you are talking about&quot;.<p>Thanks to Dunning-Kruger, it&#x27;s quite difficult to be sure if they just can&#x27;t be bothered to explain what I don&#x27;t understand (maybe performance differences arise elsewhere... maybe there were far more sophisticated tricks in the modern message dispatch code than I&#x27;d come to understand... though it seemed unlikely they&#x27;d be so significant) or its the other way around.<p>Empirical evidence would seem to point strongly in my favour, but you&#x27;d think that&#x27;d give people some pause before making such statements.
