Interesting, escripts should have worked by then. I assume this was quite some time ago, so you don't have it around anymore, but if you do recall what went wrong I would love to take a look at it. But just to put things in perspective, v1.3 is almost three years old and things have generally evolved since.

Well, sometimes the killer feature is having all of that in the same package: immutability, concurrent primitives, scripts, etc.
There are also killer features (although I guess "killer" will depend on the person) that we get from running on the Erlang VM: focus on fault-tolerance and supervisors, concurrency and distribution out-of-the-box, and generally other features coming from processes and the actor model. For example, Phoenix makes an excellent use of all those features to build performant web applications with a focus on real time (Phoenix LiveView being a recent great example). Nerves uses the fault tolerance bits for building embedded software. Etc.
