You need the GIL to access the CPython interpreter. You did not suggest anything that will change that.

No, you just misunderstood how the GIL works.

You seem to think the GIL serializes Python threads. But what it serializes is access to the CPython interpreter.

When Python threads process data in C land they don't need the GIL and can run freely.
