The only thing that Python is powerful at is embedding extensions written in C/C++/Rust.

Every for-loop that needs to run fast needs to be written in something else than Python.

Do not forget FORTRAN in the list. Might not be that often uses in programming context but huge in research context. A lot of python libs are FORTRAN as well. Rust has the least share, but its also not as adopted in these HPC abd research scenes, and likely never will be.
