Question- the article&#x27;s premise seems to be that a language&#x27;s popularity may be based on timing and language features, as opposed to language authors &quot;selling&quot; their language. How did Perl and Python gain &quot;traction&quot;, if you will? Was it organic and due to people finding them and seeing they were better, or due more to Larry and Guido pushing the languages and getting the word out, or other factors, or a combination?
