It's super exciting, but the JIT in its current form doesn't offer the kind of speedup that something like FFI into Rust or C provides. Also there are lots of great libraries in the Rust/C ecosystems that sometimes you need. Fortunately FFI is not hard, and with the relatively recent addition of dirty schedulers and with the Rustler library, it doesn't block the schedulers and it is safe, which were the two biggest issues.
