A very interesting language on powerful platform with a promising web framework. Many saw it, myself included, as a Ruby / Rails Improved, and expected its quick growth.
Unfortunately, initial enthusiasm a few years ago did lead to its wide adoption.
I talked with a couple of companies that jumped on it initially, but later decided to move to Java, Kotlin, Go. The main reason was difficulty to hire engineers to scale up quickly (in Europe), not some technical disappointments.
Sadly, it seems that being a scalable platform is not enough to scale up to business needs.
