"I can learn Go or code stuff in Python (or even Java/C#) which 99% of the cases is fast enough I used to advocate for complex stuff, but now I think differently. Solve my problem, I don't care about religious issues."

This sounds like it's written in the hobbyist/lone tinkerer/ deploying to self managed server context.

When discussing could anything replace C++ one is usually in the context of a massive business environment pending on millions of lines of C++ and native bindings, not figuring out how to write a handy personal tool.

For handy personal tools, Python is probably much better than C++ 99% of time, but when discussing, how to replace a language in an entrenched ecological slot with a huge number of interdependencies things are really not that simple at all.
