~Zero build time Python vs 20 min for Rust web app

It's more than zero, but 15 seconds would be a great deal more realistic for an incremental build.

Go is pretty close to 0 as well IME.

Funnily enough, last week I was working on parsing some json. I wrote a little script in python, tested it and then ran it over the main dataset. It took so long that I rewrote it in C# before the python script had finished!

I have a whole section in my global AGENTS.md about how python sucks to influence agents to not use it for anything performance sensitive.

My favorite improvement example was something a bit of a slog was taking 20 minutes in python, I told the agent to rewrite it in rust and the result was 300,000 times faster... 20 minutes to ones of milliseconds. Obviously not just a python problem but better solutions just seem to fall out of Rust and Python is just slow.
