True enough, but I do think there might be a lot of validity in the comparison with hurd. After all, Hurd is still under development, but there is little question that it has been eclipsed by Linux. While many have certainly become aware of the advantages of Lisp, they also want something that just works as much as possible, and the large collection of Java libraries will be a great help in this regard. By the time that arc is "ready" to be the 100 year language, it may be that it is too late to gain acceptance.

Still, I'll admit that only time will tell. Both languages are still quite young, and it is hardly uncommon for languages to develop slowly in obscurity before rising to prominence. Maybe it will gain traction, maybe it won't, but either way I think we will benefit from the increase in competition and the ideas that are generated in its creation.
