The problem is that AI has been dominating the conversation for so many years, and they'll get more improvements from removing the GIL than they would from adopting the PyPy JIT.

The JIT would help everyone else more than removing the GIL, I wish PyPy became the reference implementation during 2.7

Actually because AI has been driving the conversation that CPython JIT efforts are finally happening and being upstreamed.

It is also because of AI, that Intel, AMD and NVidia are now getting serious about Python GPU JITs, that allow writing kernels in a Python subset.

To the point that I bet Mojo will be too late to matter.
