I'm not fully sure what this means but perhaps you're right about Python given its use by data engineers, academics, SREs (though they're mainly Go these days ... which also lacks fully stable native SIMD support). Otherwise though I'd say the rest are used almost exclusively by software engineers. Unless I'm misunderstanding you.

Still hidden behind an experimental flag but SIMD is fully functional in Go: https://pkg.go.dev/simd/archsimd
