The way to combat that IMO is to continue to innovate the language improving both the language and the context it runs in (tooling, ecosystem, etc) making it easier to use, more robust, minimize the costs/benefits of changing, etc. Having a great working functional language with access to a large ecosystem and decent tooling makes adoption easier and less risky. There's more to a language choice than features; it has to work for the dev's, the organization and it has to scale to the "good but not passionate" developer.
