I disagree with this :)

I think Python has efficient IO concurrency built-in already with async, and I feel it is likely that it finds a way to work out CPU bound concurrency long-term, as projects like sub-shells with channel communication demonstrate.

Efficient CPU concurrency needs either fine-grained locking (and removal of GIL), or data immutability.

Both seem rather hard to implement.

I predict that for CPU-intensive tasks, you'll keep using extensions in native code (like numpy or pytorch), or keep passing serialized objects through queues in multiprocessing setups.
