I've rewritten a python tool in go, 1:1. And that turned something that was so slow that it was basically a toy, into something so fast that it became not just usable, but an essential asset.

Later on I also changed some of the algorithms to faster ones, but their impact was much lower than the language change.

I don’t know if people think this way anymore, but Python gained traction to some degree as a prototyping language. Verify the logic and structures, then implement the costly bits or performance sensitive bits in a more expense-to-produce more performant language.

Which is only to say: that rewrite away from python story can also work to show python doing its job. Risk reduction, scaffolding, MVP validation.
