Definitely not dead -- it got stalled for a while because Urbit tends to use deep stacks and both Graal and the JVM seem to favor shallow ones. The author (not me) came up with a "meta-stack" design that may mitigate this issue and will go back and try it soon.
But the performance seen on a trivial Ackerman function was very good -- Nock via Graal got close to C performance. That's impressive for what's basically a Lisp.
