I get it that programming languages are quite different from most of other projects in that normal projects can have a small user base and still be considered a success in solving a given problem, but with programming languages the mere fear of not being able to reach a sizeable community is enough to not even try out a new approach.
Nevertheless I think there is space for experimental/research languages. Just don't burden yourself thinking in terms of "this is the next great thing" and it will be fun, and perhaps your work and the ideas underlying it will even leave a mark, even if that doesn't necessarily mean that the particular incarnation of that particular language will ever reach adoption.
We not only stand on the shoulder of giants. We all stand on the shoulders of billions of dwarfs.
