CPython current state is more a reflection of resources spent, than what is possible.

See experience with Smalltalk and Self, where everything is dynamic dispatch, everything is an object, in a live image that can be monkey patched at any given second.

PyPy and GraalPy, and the oldie IronPython, are much better experiences than where CPython currently stands on.

Python is worse, but not by all that much. After all, PyPy has been several times faster for many years.
