> dropping the legacy C interface to Python objects. This is nonsense. No language ever will have linear algebra or numeric implementations faster than Fortran/C implementations of BLAS, LAPACK etc. Not being able to make ffi calls makes python essentially unusable for most of its niche uses. > JS has exactly none of the features that comment claims would be necessary for performance. I don't see people doing ML, scientific computing etc in JS.

C++ is pretty close to it.

  C++ compilers can and do (g++, clang++) use pretty much the same set of optimization techniques used by C compilers.

    And even offer REPL and Jupiter notebooks, so..

You're confusing "no FFI whatsoever" with "a sane FFI". Python's legacy interface is insane--it exposes virtually all details of the CPython interpreter to C extensions such that any deviation from CPython's implementation is effectively a breaking change.
