It seems serious parallel programming has mostly gone with shader/ISPC style data-parallel computation with low-level languages and the old school threads & locks model has been relegated to a side support role lost except on the CPU side. There's interesting stuff going on in the VHLL world with languages like Futhark, Jax, Mojo, etc that would be a better peer group for Python and its high level of abstraction.
