@xalynn Crystal in my startup is now the default language for everything. We are building a new open source cloud computing orchestrator, Airsailer
In my opinion, Crystal is already an excellent and mature language and it is up to each one of us to build what we need.
About popularity and being ready for enterprise use-cases, it is just a matter of time (“when”, not “if”). Companies that understand Crystal is a competitive advantage, they will be ahead and build what is missing for them.
