Which one is more likely to succeed: clojure or arc?

Now, it's pretty obvious that clojure has succeeded, and arc is most likely dead. Paraphrasing Steve Yegge, "Rich Hickey torvalds-ed Arc into obsolescence".<p>Once Clojure in Clojure gets further along and Clojure becomes even more portable, it'll be even better.

Other than not minding so much about the JVM thing (even though Clojure.NET is coming along) I find my answer still holds up pretty well after all this time :)

Clojure sounds cool, I even read the book and enjoyed it a lot, but at the end of the day it is still tainted by the ugliness of Java. If I learn a completely new language, why not use the opportunity to get rid of Java once and for all?<p>Arc could be that one language that is not missing anything (once more libraries become available).
