There is a benefit in being able to read and understand your code. If you’re most proficient in Python, it’s reasonable to want to stay there, perhaps looking to PyPy.

Also, of course, the majority of SaaS apps (perhaps most apps in general?) are not compute-bound, so gains from performance alone shouldn’t be the only metric.

My current job has a mix of Python and Go. Personally, I dislike Go. I don’t like its syntax, I don’t like its utter lack of formatting standards (gofmt is not a standard; also it sets tabs - ugh), I don’t like its insistence on static linking, and I don’t like how people claim it’s a great scripting language when you can’t just run a file on its own (and its stdlib is weak sauce compared to Python).

For a lot of scripts (think replacement to bash scripts - perhaps even one-offs), Python will save time over rust compilation times.

Why not convert to assembly?
