> IMHO python is actually undervalued. It was kind of shit at all of this for a long time. But they are making a lot of progress modernizing the language and platform and are addressing its traditional weaknesses. Better interpreting and jit performance, removing the GIL, async support that isn't half bad, etc.
The issue with Python isn't just the GIL and lack of support for concurrency. It uses dynamic types (i.e. variant types) for everything. That's way too slow, it means every single variable access must go through a dispatch step. About the only thing Python has going for it is the easy FFI with C-like languages.

That’s why I’m quite excited about Cinder, Meta’s CPython fork, that lets the programmer opt in “strict modules” and “static Python”, enabling many optimizations.
