It's a lot more like buying a board planing robot cell, replacing the robot with a human operator because you couldn't get a teach pendant for it, replacing the automated part loading/unloading because you're now running parts that your fixtures can't handle, and ultimately replacing your low-cycle-time planer with a Powermatic because the vendor went under and you can't get any spare parts. Now you just have a Powermatic with a human operator and a distant memory of your initial machine.

You (at least should be) picking oddball stuff like Clojure because the unique advantages outweigh the problems. If you're just using it as a wrapper over another language that doesn't provide those advantages, you're taking the balls off the bull, and you probably should have just used Java, C#, Go, etc.
