It's doable. Erlang is used to talk to the hardware and C code. Can build a C functions (NIF), an driver (for IO for example), spawn a process, or implement the logic of Erlang distribution protocol (what is used to talk between VMs) in C. With 20.0 coming up it will be even easier. A nifty feature called "dirty schedulers" will become stable and so building long-running calculation in C will be much easier. Previously had to take care not to block the running scheduler thread. All-in-all Erlang is really good at connecting to and managing things, C and hardware being one of those things.
