I'm not saying that at all. But looking at a feature matrix or hearing from a fan what the great parts of a language are isn't enough to convince me to adopt it.
If it's been around for 2 decades and hardly has any adoption by large companies[0] I personally am not willing to learn it (unless that changes).
I'm not necessarily using adoption as a proxy for quality either. If there isn't any meaningful adoption it's not like I can join a company to write it or have an easy time convincing my manager to try it. It could be the greatest language on earth but if I can't write it then it doesn't matter.
