That just depends on your background. For a bunch of us folks who come from a non-JVM background, we could say the same about Java. Really, Java and JS are the two biggest language communities in the world, with phenomenal feats of engineering in their runtimes, and a whole host of things to complain about. Since CLJ and CLJS are tied in this regard, I still think the startup time is the only differentiable factor in my proposed hypothetical future.
With CLJS on Node booting up as fast as it does, I can envision a world where CLJS is vastly more popular than CLJ, since it's able to deliver a class of experience prohibited by the slow JVM startup. All the other common criticisms are shared by both CLJ and CLJS, so there's a chance that, eventually, CLJ only has the startup time as a knock against it, and CLJS has no such shortcomings. (Ignoring, of course, "Lisp is weird".. don't get me started.)
That all said, I think all 'piles-to-JS language bets are off in the face of WASM.
