TL;DR
>I'll preface this by saying that neither of us has a lot of experience writing Python async code

The best advice for a start-up is to use the tools that you know best. And sometimes that's not the best tool for the job. Let's say you need to build a CLI. It's very likely that Go is the best tool for the job, but if you're a great Python programmer, then just do it in Python.
Here's a clearer case where the author was not very good with Python. Clearly, since they actually used Django instead of FastAPI, which should have been the right tool for the job. And then wrote a blog post about Python being bad, but actually it's about Django. So yeah, they should have started with Node from day one.
Actually after having written a complex CLI in Node, I think I would've been better off learning Go and writing in that.
Sometimes tools are worth learning!
I'd also rather write a CLI in Python than in Node
The only issue with writing a CLI in Node is ecosystem. The CLI libraries for Node are (or were last time I checked) inspired by React. Not a paradigm that is fun to write in, and if I'm making a CLI tool it is because I am bored and want to make something for my own entertainment.
Here is an unwanted advice from a old dog, you don't need any libray to write CLIs.
A function to display help, and another old to parse the CLI parameters isn't PhD level coding.
Also nowadays, any LLM friend can quickly generate them.
Yeah the last CLI app I used was actually a TUI. It routed std out and std err from scripts and programs it'd call out to into separate windows. It had animations and effects and a help system built in. It also had theming support because the library I used for the TUI happened to have that and came with some default themes! It was a bit beyond a simple CLI tool.
If I'm farfing around with the console I'm going to have fun.
There are also CLIs actually written in React using Ink
I'm aware....
That is exactly what I am complaining about.
I guess some people like it, but just, ick.
Gemini CLI used it, and I actually hate the layout. Never thought I'd see a CLI manage to waste terminal window space to the point of needing to zoom it out.
They were good but no experience with python async
