Competent developers can be good in <i>any</i> language. Bad developers are bad <i>regardless of language</i>.<p>You don&#x27;t hear people say things like &quot;Oh, that guy was an amazing &lt;language&gt; developer, and could build awesome, solid easy-to-read and high-performance code, but his &lt;other_language&gt; code is so bad nothing short of a complete rewrite can help&quot;.
