Any bigger than that and rust is the right hammer for my nails. Probably just personal preference, but I strongly prefer the type safety and performance guarantees of rust.
Another example is the rayon library which is incredibly succinct compared to the multiprocess module in python.
Unlikely. Python, Ruby, PHP, Javascript all do not have in-process parallelism.
In contrast, C/C++, Java/Scala/Clojure, Go, and Rust all have in-process parallelism.
This just furthers seabrookmx's point that Python and Rust belong to two different classes of useful languages.

P.S. Python's multiprocessing module is an order of magnitude better/easier than anything in the other scripting languages I listed.
Anyone reading hackernews knows that Node doesn't have an issue with popularity (and AFAIK Python doesn't either).
They're different levels of abstraction and I think are both great languages that serve different use cases.
I'm always going to be more productive in Python. And Python has an awesome ecosystem for web apps. Rust gives you native compiled binaries, concurrency, and speed in general.
Why you'd consider these two languages for the same app is beyond me.
