I spent some time looking into it. I believe it could be done with a source-to-source transpiler with zero-cost abstractions and some term rewriting. It’s a lot of work.

The real barrier my thought experiment hit were the extensions. Many uses of Python are glue around C extensions designed for the CPython interpreter. Accelerating “Python” might actually be accelerating Python, C, and hybrid code that’s CPython-specific. Every solution seemed like more trouble than just rewriting those libraries to not be CPython-specific. Or maybe to work with the accelerators better.

Most people are just using high-level C++ and Rust in the areas I was considering. If using Python, the slowdown of Python doesn’t impact them much anyway since their execution time is mostly in the C code. I’m not sure if much will change.
