So who&#x27;s making arguments without supporting facts? The Hacker Life provides evidence that startups prefer Ruby, C and Python. Fortune 500 companies may use JS for client-facing web UI applications (which are generally not mission-critical), but for heavy-duty shit, they&#x27;ll stick to Java, C#, Python, C++, etc. Show me what Fortune 500 companies are replacing these tried-and-true workhorses with JavaScript.<p>As for games, what serious gaming platform relies on WebGL? Most games are written in C++ for a reason: maximum performance. When I was Project Team Leader of the Windows NT Driver Group at ATI Technologies (now AMD), all the OpenGL software I saw was written in C++. JavaScript could <i>never</i> have been usable, even with V8.<p>Smalltalk, seriously. It&#x27;s still used today around the world by many businesses. Cincom and GemTalk are major Smalltalk vendors. I have friends working at Cherniak Software and Simberon, both important Smalltalk software houses. ESUG (European Smalltalk User Group) is a mammoth organization representing hundreds of companies using Smalltalk. What did you say about &quot;a position of obvious ignorance?&quot;
