Facebook using Haskell, or any language, does not make it less &quot;academic&quot; or more &quot;production quality.&quot;<p>Ultimately, we can use lots of different languages in different roles. People have been shipping Haskell code in production for years. The runtime and compiler have been up to snuff for some time, and honestly the build tools were not in any worse of a place than Go&#x27;s are right now.<p>The decision if something is production-ready for your shop is a matter of your personal (and&#x2F;or organizational) commitment to that technical platform. You do not need the blessing of a big company to use a tool. Perpetuating this idea only makes it harder for people to try new tools. And so long as Haskell continues to be flexible and easy to extend, it&#x27;ll still be useful to academia (hence the 100+ language extensions still available).
