Well, I really like this thing.

I like that it's a daemon. You can connect to it from various clients, do stuff, disconnect, and your stuff is still there when you come back, your processes are just running in the background. Conceptually, it's no different than SSHing into your favorite remote system.

In contrast to most other image systems, that are not, routinely, just a long running generic processor.

It's not "Lisp OS", but it's Lispy-ish OSey-ish.

They have their own cool little, byte code compiled Lisp, with the mailbox, and multi-processing intrinsic, and those isolated name spaces, which is nice. There's no shared memory, just message passing. That's fun and geeky.

Mailboxes/queues are not ubiquitous on Unix systems compared to streams and pipes and sockets. The queues, while they exist, are not readily lifted in the shells and such, so they become a specialty item.

Whereas in Unix, you can craft simple services using, well, anything, and inetd, that's still different from a long running mailbox listener.

They have different purposes, and the systems that use one as their hammer vs the other, will look different. But the important thing is making those services simple to make and use.
