I believe BEAM bytecode is now JIT-ed.

EDIT: It is, since OTP 24 was released in 2021:

> The BeamAsm JIT-compiler has been added to Erlang/OTP and will give a significant performance boost for many applications. The JIT-compiler is enabled by default on most x86 64-bit platforms that have a C++ compiler that can compile C++17.
