They all have drawbacks, but they also reduce the case for needing to speed up CPython.

Pypy does provide faster pure Python. Its a compatible implementation with JIT.

The newest version of python that PyPy supports is 3.12. CPython is on 3.15.

And from what I understand there are limitations with using libraries that use the CPython API to interface with native code.

3.12 vs 3.15 would be fine, it's not like most depend on cutting edge features.

But the libraries limitations, and that it's not the "real" Python project, do get you.

Onlything is a lot of cextensions are super slow there. that is only bottleneck left which could be solved with resources that those guys spent on experimental jit.

Different guys. The CPython guys are not those behind Pypy. And they also don't want to see Pypy replace their project.

Guido thought about it before he get into Microsoft.
