> just delegate all heavy lifting to optimized C/c++ and the likes

The more o used Python, and the more Python I saw written, the more I am convinced this is not a good or reasonable argument. A good chunk of the Python devs I’ve interacted with are mystified by the concept of virtual environments, regularly abuse global variables, struggle to read the docs, and structure their code poorly.

Telling these people “oh just write this section in C” will go nowhere. It’s asking them to figure out: installation, compilation, packaging, FFI, tool chains, and foot-guns of language(s) that are arguably more dangerous and whose operation varies from “not super straightforward” to “arcane” based on your dev and deployment environment and application needs.
