Another point is that beginner-friendly languages don't always make expert-friendly languages. Python is great for beginners, but I have seen its lack of types create heaps of brittle code at companies that no one wants to touch. Some of the "C++ contenders" (besides Rust) like Nim, Zig, and potentially Swift seem to balance this line well: simple to start using, but grow with one's expertise.
