Are you joking? Off topic? He made a comment about perl doing a poor version transition, and perl was largely replaced by python which also did a language transition. It makes complete sense to bring up python2 -&gt; python3.<p>I also made the transition to `#!&#x2F;usr&#x2F;bin&#x2F;env python3` fairly smoothly. That doesn&#x27;t mean that the majority of the community did. Python3 came out in 2008, next week will be seven years of it being out. Yet `#!&#x2F;usr&#x2F;bin&#x2F;env python` still defaults to python2[1]. That&#x27;s not quite the expected 5 years of transition that they hoped for. At year 5 it looked like this [2].<p>[1]: <a href="http:&#x2F;&#x2F;legacy.python.org&#x2F;dev&#x2F;peps&#x2F;pep-0394&#x2F;" rel="nofollow">http:&#x2F;&#x2F;legacy.python.org&#x2F;dev&#x2F;peps&#x2F;pep-0394&#x2F;</a><p>[2]: <a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20131204094939&#x2F;http:&#x2F;&#x2F;python3wos.appspot.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20131204094939&#x2F;http:&#x2F;&#x2F;python3wos...</a>
