&gt; I think it&#x27;s a risky move.<p>&gt; It&#x27;s just... wow, that&#x27;s pretty mission critical for what I gather is still a beta-phase tool.<p>I think this is very &#x27;90s thinking. Extreme &quot;if it&#x27;s not C++, you can&#x27;t deploy it!&quot; conservatism about programming languages hasn&#x27;t been true for well over a decade. Paul Graham has written some nice essays about this very phenomenon.<p>Also, Rust is not &quot;a beta-phase tool&quot;.<p>New languages are much easier to deploy since the PL Renaissance. There are a few holdout industries that still stick with C++ no matter what, such as games, but they&#x27;ll come around eventually. :)
