Discussion about things like erlang tend to go around in circles because people don't separate out the two distinct parts, the VM and the actual language. The language is niche and archaic meaning that libraries, tools, ecosystem and even syntax is a huge problem.

The VM is what people really want, but for some reason no one ever talks about using the VM with another language or cloning the VM for another language instead of trying to force the part that people don't want (language) with the part that works.
