Python 3.14's Concurrency and Parallelism Improvements: The Future of Async?
Python 3.14, releasing soon, brings significant improvements in concurrency and parallelism with PEP 779 (officially supported free threading) and PEP 734 (multiple interpreters in the stdlib). However, despite async/await existing for a decade, its adoption remains lower than expected. The article analyzes the reasons: async excels at I/O-bound tasks but is limited in areas like file I/O; the GIL restricts true parallelism in multithreading; maintaining both synchronous and asynchronous APIs increases development and maintenance costs. The author suggests that Python 3.14's new features might reduce reliance on async programming, offering more practical concurrency and parallelism solutions through free threading and multiple interpreters.
