For me async/await was a godsend. I've had so bad experiences with multithreading in C++, where I ended up in a Semaphore/Mutex hell in a big project, that async/await is a really welcome compromise between using idle CPU resources and just not doing multiple things at once.

Then there's `#[tokio::main(flavor = "multi_thread", worker_threads = 2)]` which actually lets you use multithreading with async/await which is just a nice feature to have, given that Python can't do this due to the GIL. But asyncio in Python is also so great.
