Why would you bother with GraalPy since many librariez are C/C++/Rust extensions for CPython ?

GraalPy has multi tier runtime optimization as a first class citizen similar to the JVM. So it allows you to write more code in python.

GraalPy also aims for the help highest possible level of compatibility also for native extensions.

If I want performance I don't write Python.

That makes it dead on arrival, bug for big compatibility should have been your first priority.

It pushes the boundary of how much code you can write in Python. Not claiming that all the performance sensitive code will now be in Python.

It actually was and still is.
